Numbers Chapters 18 - 20
Opening Prayer
Heavenly Father,
We come before You with grateful hearts, thanking You for the gift of Your Word and for drawing us together to study it. We honor You as our holy and faithful God, the One who provides, guides, and sustains Your people in every season.
As we open the book of Numbers and reflect on chapters 18 through 20, we ask for Your wisdom and understanding. Help us to see the importance of obedience, reverence, and responsibility in our walk with You. Teach us through the priestly duties You established, reminding us that service to You is a sacred calling and a privilege.
Lord, as we read of challenges, rebellion, and human weakness, soften our hearts to receive correction and truth. Help us to trust You even in times of frustration, waiting, and uncertainty. Where there was impatience and disobedience, show us the consequences—and where there was mercy, remind us of Your enduring grace.
Open our eyes to the lessons You desire us to learn, our ears to hear Your voice, and our hearts to be transformed by Your Spirit. May this study draw us closer to You and shape us into people who honor You with our words, actions, and faith.
We dedicate this time to You, asking that everything discussed and shared would glorify Your name and strengthen our relationship with You and with one another.
We pray all of this in the precious name of Jesus Christ,
Amen.
Looking Back
In Numbers 16–17, a major rebellion erupted against Moses and Aaron's leadership, led by Korah (a Levite) along with Dathan, Abiram, and 250 prominent men who challenged the exclusive priesthood of Aaron. God dramatically judged the rebels: the earth opened and swallowed Korah, Dathan, Abiram, and their households alive, while fire consumed the 250 men offering unauthorized incense. Despite this, the people grumbled against Moses and Aaron the next day, accusing them of killing God's people, prompting a plague that killed 14,700 Israelites until Aaron interceded with incense to stop it. In chapter 17, God confirmed Aaron's priesthood by causing his staff to bud, blossom, and bear almonds overnight among the tribal staffs, silencing further complaints.
These dramatic events of rebellion, divine judgment, and confirmation of priestly authority set the stage for the next chapters. Numbers 18–20 shift focus to regulations for the priests and Levites, the important red heifer purification ritual, the deaths of Miriam and Aaron, the incident of Moses striking the rock at Meribah, and Israel's continued journey toward the Promised Land amid ongoing challenges.
Scripture ESV
Numbers 18
Duties of Priests and Levites
1So the Lord said to Aaron, “You and your sons and your father’s house with you shall bear iniquity connected with the sanctuary, and you and your sons with you shall bear iniquity connected with your priesthood. 2And with you bring your brothers also, the tribe of Levi, the tribe of your father, that they may join you and minister to you while you and your sons with you are before the tent of the testimony. 3They shall keep guard over you and over the whole tent, but shall not come near to the vessels of the sanctuary or to the altar lest they, and you, die. 4They shall join you and keep guard over the tent of meeting for all the service of the tent, and no outsider shall come near you. 5And you shall keep guard over the sanctuary and over the altar, that there may never again be wrath on the people of Israel. 6And behold, I have taken your brothers the Levites from among the people of Israel. They are a gift to you, given to the Lord, to do the service of the tent of meeting. 7And you and your sons with you shall guard your priesthood for all that concerns the altar and that is within the veil; and you shall serve. I give your priesthood as a gift, and any outsider who comes near shall be put to death.”
8Then the Lord spoke to Aaron, “Behold, I have given you charge of the contributions made to me, all the consecrated things of the people of Israel. I have given them to you as a portion and to your sons as a perpetual due. 9This shall be yours of the most holy things, reserved from the fire: every offering of theirs, every grain offering of theirs and every sin offering of theirs and every guilt offering of theirs, which they render to me, shall be most holy to you and to your sons. 10In a most holy place shall you eat it. Every male may eat it; it is holy to you. 11This also is yours: the contribution of their gift, all the wave offerings of the people of Israel. I have given them to you, and to your sons and daughters with you, as a perpetual due. Everyone who is clean in your house may eat it. 12All the best of the oil and all the best of the wine and of the grain, the firstfruits of what they give to the Lord, I give to you. 13The first ripe fruits of all that is in their land, which they bring to the Lord, shall be yours. Everyone who is clean in your house may eat it. 14Every devoted thing in Israel shall be yours. 15Everything that opens the womb of all flesh, whether man or beast, which they offer to the Lord, shall be yours. Nevertheless, the firstborn of man you shall redeem, and the firstborn of unclean animals you shall redeem. 16And their redemption price (at a month old you shall redeem them) you shall fix at five shekels in silver, according to the shekel of the sanctuary, which is twenty gerahs. 17But the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat, you shall not redeem; they are holy. You shall sprinkle their blood on the altar and shall burn their fat as a food offering, with a pleasing aroma to the Lord. 18But their flesh shall be yours, as the breast that is waved and as the right thigh are yours. 19All the holy contributions that the people of Israel present to the Lord I give to you, and to your sons and daughters with you, as a perpetual due. It is a covenant of salt forever before the Lord for you and for your offspring with you.” 20And the Lord said to Aaron, “You shall have no inheritance in their land, neither shall you have any portion among them. I am your portion and your inheritance among the people of Israel.
21 “To the Levites I have given every tithe in Israel for an inheritance, in return for their service that they do, their service in the tent of meeting, 22so that the people of Israel do not come near the tent of meeting, lest they bear sin and die. 23But the Levites shall do the service of the tent of meeting, and they shall bear their iniquity. It shall be a perpetual statute throughout your generations, and among the people of Israel they shall have no inheritance. 24For the tithe of the people of Israel, which they present as a contribution to the Lord, I have given to the Levites for an inheritance. Therefore I have said of them that they shall have no inheritance among the people of Israel.”
25And the Lord spoke to Moses, saying, 26“Moreover, you shall speak and say to the Levites, ‘When you take from the people of Israel the tithe that I have given you from them for your inheritance, then you shall present a contribution from it to the Lord, a tithe of the tithe. 27And your contribution shall be counted to you as though it were the grain of the threshing floor, and as the fullness of the winepress. 28So you shall also present a contribution to the Lord from all your tithes, which you receive from the people of Israel. And from it you shall give the Lord’s contribution to Aaron the priest. 29Out of all the gifts to you, you shall present every contribution due to the Lord; from each its best part is to be dedicated.’ 30Therefore you shall say to them, ‘When you have offered from it the best of it, then the rest shall be counted to the Levites as produce of the threshing floor, and as produce of the winepress. 31And you may eat it in any place, you and your households, for it is your reward in return for your service in the tent of meeting. 32And you shall bear no sin by reason of it, when you have contributed the best of it. But you shall not profane the holy things of the people of Israel, lest you die.’”
Numbers 19
Laws for Purification
1Now the Lord spoke to Moses and to Aaron, saying, 2“This is the statute of the law that the Lord has commanded: Tell the people of Israel to bring you a red heifer without defect, in which there is no blemish, and on which a yoke has never come. 3And you shall give it to Eleazar the priest, and it shall be taken outside the camp and slaughtered before him. 4And Eleazar the priest shall take some of its blood with his finger, and sprinkle some of its blood toward the front of the tent of meeting seven times. 5And the heifer shall be burned in his sight. Its skin, its flesh, and its blood, with its dung, shall be burned. 6And the priest shall take cedarwood and hyssop and scarlet yarn, and throw them into the fire burning the heifer. 7Then the priest shall wash his clothes and bathe his body in water, and afterward he may come into the camp. But the priest shall be unclean until evening. 8The one who burns the heifer shall wash his clothes in water and bathe his body in water and shall be unclean until evening. 9And a man who is clean shall gather up the ashes of the heifer and deposit them outside the camp in a clean place. And they shall be kept for the water for impurity for the congregation of the people of Israel; it is a sin offering. 10And the one who gathers the ashes of the heifer shall wash his clothes and be unclean until evening. And this shall be a perpetual statute for the people of Israel, and for the stranger who sojourns among them.
11 “Whoever touches the dead body of any person shall be unclean seven days. 12He shall cleanse himself with the water on the third day and on the seventh day, and so be clean. But if he does not cleanse himself on the third day and on the seventh day, he will not become clean. 13Whoever touches a dead person, the body of anyone who has died, and does not cleanse himself, defiles the tabernacle of the Lord, and that person shall be cut off from Israel; because the water for impurity was not thrown on him, he shall be unclean. His uncleanness is still on him.
14“This is the law when someone dies in a tent: everyone who comes into the tent and everyone who is in the tent shall be unclean seven days. 15And every open vessel that has no cover fastened on it is unclean. 16Whoever in the open field touches someone who was killed with a sword or who died naturally, or touches a human bone or a grave, shall be unclean seven days. 17For the unclean they shall take some ashes of the burnt sin offering, and fresh water shall be added in a vessel. 18Then a clean person shall take hyssop and dip it in the water and sprinkle it on the tent and on all the furnishings and on the persons who were there and on whoever touched the bone, or the slain or the dead or the grave. 19And the clean person shall sprinkle it on the unclean on the third day and on the seventh day. Thus on the seventh day he shall cleanse him, and he shall wash his clothes and bathe himself in water, and at evening he shall be clean.
20“If the man who is unclean does not cleanse himself, that person shall be cut off from the midst of the assembly, since he has defiled the sanctuary of the Lord. Because the water for impurity has not been thrown on him, he is unclean. 21And it shall be a statute forever for them. The one who sprinkles the water for impurity shall wash his clothes, and the one who touches the water for impurity shall be unclean until evening. 22And whatever the unclean person touches shall be unclean, and anyone who touches it shall be unclean until evening.”
Numbers 20
The Death of Miriam
1And the people of Israel, the whole congregation, came into the wilderness of Zin in the first month, and the people stayed in Kadesh. And Miriam died there and was buried there.
The Waters of Meribah
2 Now there was no water for the congregation. And they assembled themselves together against Moses and against Aaron. 3And the people quarreled with Moses and said, “Would that we had perished when our brothers perished before the Lord! 4Why have you brought the assembly of the Lord into this wilderness, that we should die here, both we and our cattle? 5And why have you made us come up out of Egypt to bring us to this evil place? It is no place for grain or figs or vines or pomegranates, and there is no water to drink.” 6Then Moses and Aaron went from the presence of the assembly to the entrance of the tent of meeting and fell on their faces. And the glory of the Lord appeared to them, 7and the Lord spoke to Moses, saying, 8“Take the staff, and assemble the congregation, you and Aaron your brother, and tell the rock before their eyes to yield its water. So you shall bring water out of the rock for them and give drink to the congregation and their cattle.” 9And Moses took the staff from before the Lord, as he commanded him.
Moses Strikes the Rock
10Then Moses and Aaron gathered the assembly together before the rock, and he said to them, “Hear now, you rebels: shall we bring water for you out of this rock?” 11And Moses lifted up his hand and struck the rock with his staff twice, and water came out abundantly, and the congregation drank, and their livestock. 12And the Lord said to Moses and Aaron, “Because you did not believe in me, to uphold me as holy in the eyes of the people of Israel, therefore you shall not bring this assembly into the land that I have given them.” 13These are the waters of Meribah, where the people of Israel quarreled with the Lord, and through them he showed himself holy.
Edom Refuses Passage
14 Moses sent messengers from Kadesh to the king of Edom: “Thus says your brother Israel: You know all the hardship that we have met: 15how our fathers went down to Egypt, and we lived in Egypt a long time. And the Egyptians dealt harshly with us and our fathers. 16And when we cried to the Lord, he heard our voice and sent an angel and brought us out of Egypt. And here we are in Kadesh, a city on the edge of your territory. 17Please let us pass through your land. We will not pass through field or vineyard, or drink water from a well. We will go along the King’s Highway. We will not turn aside to the right hand or to the left until we have passed through your territory.” 18But Edom said to him, “You shall not pass through, lest I come out with the sword against you.” 19And the people of Israel said to him, “We will go up by the highway, and if we drink of your water, I and my livestock, then I will pay for it. Let me only pass through on foot, nothing more.” 20But he said, “You shall not pass through.” And Edom came out against them with a large army and with a strong force. 21Thus Edom refused to give Israel passage through his territory, so Israel turned away from him.
The Death of Aaron
22And they journeyed from Kadesh, and the people of Israel, the whole congregation, came to Mount Hor. 23And the Lord said to Moses and Aaron at Mount Hor, on the border of the land of Edom, 24“Let Aaron be gathered to his people, for he shall not enter the land that I have given to the people of Israel, because you rebelled against my command at the waters of Meribah. 25Take Aaron and Eleazar his son and bring them up to Mount Hor. 26And strip Aaron of his garments and put them on Eleazar his son. And Aaron shall be gathered to his people and shall die there.” 27Moses did as the Lord commanded. And they went up Mount Hor in the sight of all the congregation. 28And Moses stripped Aaron of his garments and put them on Eleazar his son. And Aaron died there on the top of the mountain. Then Moses and Eleazar came down from the mountain. 29And when all the congregation saw that Aaron had perished, all the house of Israel wept for Aaron thirty days.
What does this scripture mean?
Numbers 18–20 addresses the establishment and support of the priesthood, purification from death's impurity, and critical leadership failures as Israel resumes its wilderness journey after the earlier rebellions.
· Chapter 18 details the duties and privileges of the priests (Aaron and his sons) and the Levites. Following the confirmation of Aaron's priesthood, God reaffirms that the priests bear responsibility for the sanctuary and altar, with the Levites assisting but not encroaching on priestly roles (under penalty of death). The priests receive no land inheritance in Canaan—instead, God Himself is their portion and inheritance (Numbers 18:20)—and they are supported through tithes, offerings, firstfruits, and firstborn redeemable portions from the people. The Levites, in turn, receive the Israelites' tithes but must tithe a tenth of that to the priests. This system underscores God's provision for those dedicated to His service and the holiness required in approaching Him.
· Chapter 19 introduces the unique ritual of the red heifer (a spotless red cow never yoked), burned outside the camp with cedar, hyssop, and scarlet wool. Its ashes are mixed with water to create "water of cleansing" for purifying people or objects defiled by contact with a corpse. This ordinance provides a means of ritual purification from death's impurity, symbolizing how God supplies grace and restoration even amid the consequences of sin and mortality.
· Chapter 20 recounts events in the wilderness of Zin: Miriam dies and is buried at Kadesh; the people complain about lack of water, leading to the incident at Meribah where God instructs Moses to speak to the rock for water, but Moses strikes it twice in frustration and unbelief. God provides water anyway but judges Moses and Aaron for not upholding His holiness before the people, declaring they will not enter the Promised Land. Aaron dies on Mount Hor, with his garments transferred to his son Eleazar as successor to the high priesthood.
Overall, these chapters emphasize God's order for worship and leadership, His provision for holiness and purification, and the serious consequences of failing to honor Him fully—even for faithful leaders like Moses and Aaron—while showing His continued faithfulness to supply needs and guide Israel toward the land despite their (and their leaders') shortcomings. This section bridges the rebellion narratives with the approaching conquest, highlighting themes of priesthood, purity, obedience, and divine judgment tempered by grace.
What it means for us today
Numbers 18–20 has profound application for believers today, pointing forward to Jesus Christ and shaping how we approach worship, leadership, holiness, purification, and obedience under the New Covenant.
God's Order for Worship and Leadership
In the Old Testament, God established a clear hierarchy: the high priest (Aaron), his sons as priests, and the Levites as assistants, with strict boundaries to protect the holiness of God's presence. The priests received no land inheritance—God Himself was their portion (Numbers 18:20), and the people supported them through tithes and offerings.
Today, under the New Covenant, Jesus is our great High Priest (Hebrews 4:14–16; 7:24–25), and all believers are a "royal priesthood" (1 Peter 2:9). There is no longer a mediating class of priests; we have direct access to God through Christ. This means worship is no longer confined to rituals or a temple but is offered "in spirit and truth" (John 4:23–24), through prayer, Scripture, community, and daily living as living sacrifices (Romans 12:1). Leadership in the church—pastors, elders, etc.—serves humbly, not lording over others, but equipping believers for ministry (Ephesians 4:11–12). God's provision remains: He sustains those who serve Him faithfully, often through the generosity of His people, and our ultimate inheritance is in Him, not earthly possessions.
Provisions for Holiness and Purification
The red heifer ritual (Numbers 19) provided cleansing from corpse impurity (symbolizing defilement by death/sin), using ashes mixed with water for purification. This was a gracious means to restore fellowship despite contact with death's consequences.
For us today, this foreshadows Christ's perfect sacrifice. Jesus, sinless and unblemished, died "outside the camp" (Hebrews 13:11–13), purifying us once for all from sin's defilement. His blood and the "water" of the Spirit cleanse us (1 John 1:7–9; Titus 3:5). We no longer need ritual ashes; confession and faith in Christ's finished work purify us continually. Holiness remains essential—we are called to pursue it (Hebrews 12:14), avoiding sin that grieves the Spirit and hinders fellowship, while relying on God's grace for restoration.
Consequences of Disobedience
Even Moses and Aaron, faithful leaders, faced judgment for failing to honor God's holiness at Meribah: Moses struck the rock twice instead of speaking to it, taking credit ("must we fetch you water?") and misrepresenting God. As a result, they were barred from entering the Promised Land (Numbers 20:12). This shows that higher responsibility brings stricter accountability—disobedience has real consequences, even for God's chosen servants.
Today, this warns believers (especially leaders) against unbelief, frustration-driven actions, or misrepresenting God's character. Disobedience can lead to lost blessings, diminished influence, or discipline (Hebrews 12:5–11), though not loss of salvation for those in Christ. It reminds us to obey precisely, trust God's word over emotions, and glorify Him alone. Yet God's faithfulness endures—He still provided water despite Moses' failure, just as He remains gracious to us through Christ.
In summary, these chapters call us to honor God's holiness in worship and leadership, rely on Christ's perfect purification, support His work generously, and obey faithfully, knowing both the privilege of direct access to God and the seriousness of representing Him well. Through Jesus, we enter the ultimate "Promised Land" of eternal rest, sustained by grace.
What would you teach someone if you could pick on thing to teach?
If I could teach one core lesson from Numbers 18–20 that could truly transform a person's life today, it would be this: Honor God's holiness by trusting and obeying Him precisely—even when frustrated, exhausted, or feeling justified in your anger—because disobedience, no matter how small it seems, has real consequences, yet God's grace and provision remain faithful.
This lesson centers on the dramatic failure at Meribah in Numbers 20. Moses, after decades of faithful leadership, enduring endless complaints, and seeing God's power repeatedly, snaps. Instead of speaking to the rock as God commanded (a simple act of faith that would glorify God's word), he strikes it twice in frustration, saying, "Listen now, you rebels; shall we bring forth water for you?" (v. 10). Water flows anyway—God still provides—but Moses and Aaron are barred from entering the Promised Land because they "did not believe in [God], to uphold [Him] as holy in the eyes of the people" (v. 12).
Why this one lesson impacts life today
· It exposes the danger of unchecked emotions overriding obedience. In our high-stress world—family conflicts, work pressures, church frustrations, or personal burnout—it's easy to justify bending God's clear instructions ("just this once," "they deserve it," "I'm too tired"). Moses' moment reminds us that higher responsibility (and even long faithfulness) doesn't grant a pass on precise obedience. Partial obedience is disobedience, and it can cost us blessings, influence, or deeper intimacy with God.
· It highlights the weight of representing God. As believers, we are all "priests" (1 Peter 2:9) called to reflect His character. When we react in anger, take credit ("we provide"), or misrepresent His patience and holiness, we obscure His glory to others—just as Moses did.
· It balances warning with hope. God didn't abandon Israel; He still gave water. He disciplined Moses but preserved the nation's path to the land. Today, through Christ (the true Rock struck once for us, 1 Corinthians 10:4), we have forgiveness and restoration when we fail (1 John 1:9). Discipline comes as loving correction (Hebrews 12:5–11), not rejection.
Practical takeaway to live by
Guard your heart against frustration turning into unbelief. When tempted to lash out or shortcut God's way, pause and ask: "Am I upholding God's holiness here, or am I taking matters into my own hands?" Choose to speak truth in love, trust His provision, and give Him glory—even in dry seasons. This habit of precise, faith-filled obedience, rooted in reliance on Christ, protects your walk, blesses others, and keeps you aligned for the "Promised Land" of eternal rest with Him.
Master this, and it changes everything: relationships heal, leadership strengthens, and your life more faithfully points to the God who provides despite our flaws.
Closing Thought
As we close today’s lesson, Numbers 18–20 reminds us that walking with God is both a privilege and a responsibility. God calls His people to honor His holiness, trust His instructions, and represent Him faithfully—especially during times of frustration, weariness, or challenge.
We see that even faithful leaders like Moses and Aaron were held accountable when they allowed emotion to override obedience. This teaches us that obedience is not only about what we do, but how we trust God in difficult moments. Yet we also see God’s grace: He continued to provide water for His people and remained faithful to lead them forward.
For us today, this passage encourages us to walk humbly, obey God fully, and rely on His grace when we fall short. Through Jesus Christ, our perfect High Priest, we are forgiven, restored, and strengthened to keep walking with Him—even through wilderness seasons. May our lives reflect His holiness, trust His provision, and give Him glory in all things. Thank you for joining me and I hope you have a blessed day. I love you.
