This chapter begins by reminding us that God spoke to Moses at Mount Sinai and that the sons of Aaron, who was Moses’ brother, were specifically anointed and ordained to the Lord as the high priests. From Aaron, priests were to come to minister the services of the tabernacle, Numbers 3:1-3.
Notice that Nadab and Abihu, two sons of Aaron sinned against the Lord, and as a result, they were struck dead, Numbers 3:4 / Leviticus 10:1-2. It appears that Eleazar and Ithamar inherited the priesthood and passed it down to their sons after them, Numbers 3:4 / Exodus 6:23 / Exodus 30:30.
Here we read that the sons of Levi helped in their duties as priests with the sons of Aaron, Judges 17:5 / Judges 17:10 / Judges 17:13. It’s at this point in time that the tribe of Levi was separated from the other tribes of Israel so that they can focus on ministering to the spiritual needs of the nation, Numbers 3:5-7 / Numbers 8:11.
They are to take care of all the furnishings of the tent of meeting, fulfilling the obligations of the Israelites by doing the work of the tabernacle, Numbers 3:8. The Levites are to be given to Aaron and his sons and who are to be given wholly to him, Numbers 3:9.
Notice that if anyone else approached the sanctuary they were to be put to death, Numbers 3:10 / Numbers 3:38. This tells us that no one or anything unclean was allowed to do the tasks which were given specifically only to the Levites. God says the Levites are His, all the firstborn are His, in other words, the firstborn belonged to God, Leviticus 3:11-13.
Constable, in his commentary, says the following.
‘God selected the Levites and their cattle in place of the first-born. God bestowed this privilege on the Levites because they stood with God when the rest of the nation apostatized by worshipping the golden calf, Exodus 32:26-29.
God had consecrated the firstborn of Israel at the time of the exodus from Egypt, Exodus 13:2 / Exodus 13:11-12. God didn’t want human sacrifice, so He took the tribe of Levi as Israel’s firstborn. Instead of taking all the firstborn of Israel, He took only the sons of Levi.
Coffman, in his commentary, says the following.
‘There is important symbolism in this. ‘As representatives of the hallowed first-born, Exodus 22:29-30 / Exodus 34:19-20, the Levites picture the saints composing ‘the church of the first-born, written (registered) in heaven,’ Hebrews 12:23, having no earthly inheritance, but a heavenly place and service.’
In the Desert of Sinai, Moses is told to count the Levites by their families and clans, Numbers 3:14. We read that the census included counting all the male children who were over one month old, Numbers 3:15-16. It also included counting the children between the ages of thirty and fifty. The total number of the males between thirty and fifty was 8,580, Numbers 4:48. Those between thirty and fifty would care for the tabernacle under the supervision of the sons of Aaron.
They were to be grouped by the families, with the main grouping according to Levi’s three sons, Gershon, Kohath, and Merari, Numbers 3:17 / Genesis 46:11. The counting included the Gershonites, Kohathites, Merarites, with Moses and Aaron.
Gill, in his commentary, says the following, concerning Libni and Shimei, the sons of Gershon, Numbers 3:18.
‘Who are elsewhere mentioned as his sons, Exodus 6:17, and from hence were the families of the Libnites and Shemites, as in Numbers 3:21.’
Kohath was the second son of Levi, Numbers 3:19.
Gill, in his commentary, says the following, concerning Amram, and Izehar, Hebron, and Uzziel the sons of Kohath, Numbers 3:19.
‘So in Exodus 6:18, and from whom were named the family of the Amramites, to which Moses and Aaron belonged, and the families of the Izeharites, Hebronites, and Uzzielites, as they are called, Numbers 3:27.’
Merari was the third son of Levi, Numbers 3:20.
Gill, in his commentary, says the following, concerning Mahli and Mushi the sons of Merari, Numbers 3:20.
‘The same as in Exodus 6:19, from whom were denominated the families of the Mahlites and Mushites, who, as the preceding families, were numbered at this time.’
Gershon was the first son of Levi, Numbers 3:21. The Gershonites were to camp westward to the tabernacle which is in between Judah and the tabernacle itself, Numbers 3:21-23. Their job was to take care of the skins that covered the tabernacle itself, Numbers 3:24-26 / Exodus 26:14 / Exodus 26:1 / Exodus 26:7 / Exodus 26:36 / Exodus 27:9 / Exodus 27:16.
Kohath was probably a cousin of Moses, Numbers 3:27. They served in taking care of the ark and ceremonial utensils and they were responsible for the transportation of the ark and ceremonial utensils, Numbers 3:28-32 / Numbers 4:32.
Gill, in his commentary, says the following, concerning Elizaphan, Numbers 3:30.
‘The same man, who, with his brother Mishael, carried Nadab and Abihu out of the camp, and buried them, Leviticus 10:4, he descended from the last and youngest of the families of the Kohathites; and some think this was one reason at least of Korah’s dissatisfaction, and of his entering into a conspiracy against Moses and Aaron, because one of a younger family of his house was preferred to this dignity before him.’
The family of Merari were to camp northward to the tabernacle, Numbers 3:33-35, in between Dan and the tabernacle itself. Their job involved taking care of the structural aspects of the tabernacle, that is, the pillars, the boards, and so forth, Numbers 3:36-37 / Exodus 26:26 / Exodus 26:32 / Exodus 26:19 / Exodus 27:9 / Exodus 27:19.
The total number of males one month and older was 22,000, Numbers 3:39. The total number that is given in Numbers 3:39, doesn’t include an additional three-hundred. The three-hundred were possibly the firstborn of the Levites, and so, didn’t need to be counted with the total number since they were already consecrated to the Lord. I’m sure those of you who are good at maths would have noticed that the numbers don’t add up.
Barnes, in his commentary, says the following.
‘A number on which the commutation with the firstborn of the twelve tribes depends, Numbers 3:43-46. The actual total of the male Levites is 22,300, Numbers 3:22 / Numbers 3:28 / Numbers 3:34, and the extra 300 are considered by some to represent those who, being first-born themselves in the tribe of Levi, could not be available to redeem the first-born in other tribes.’
Wenham, in his commentary, says the following.
‘The total of 22,000 Levites given in Numbers 3:39, does not tally with the totals of the individual clans given in Numbers 3:22 / Numbers 3:28 / Numbers 3:34 which come to 22,300. The discrepancy is most easily explained as textual corruption in Numbers 3:28. The number of Kohathites may originally have been 8,300. 3, Hebrew ‘sls’, could quite easily have been corrupted into 6, ‘ss’.’
Moses, Aaron, and his sons were to camp to the east of the tabernacle, Numbers 3:38. They were responsible for the care of the sanctuary on behalf of the Israelites, Numbers 3:38. Anyone else who approached the sanctuary was to be put to death, Numbers 3:38 / Numbers 3:10.
Moses is to count all the firstborn Israelite males who are a month old or more and make a list of their names, Numbers 3:40. He is to take the Levites for God in place of all the firstborn of the Israelites, and the livestock of the Levites in place of all the firstborn of the livestock of the Israelites, Numbers 3:41.
Coffman, in his commentary, says the following.
‘It is significant that in the case of the cattle mentioned here, there was evidently permitted a redemption, through exchange, of both clean and unclean animals, some of which, according to legislation in Numbers 18:15-17, had to be sacrificed and not redeemed. Obviously, this was a special case not subject to normal requirements.’
Remember there were 22,273 firstborn sons in Israel, Numbers 3:42-43, and there were only 22,000 Levite males, Leviticus 3:39, so we have a difference of 273 between the final total of the firstborn and the total of the tribe of Levi. To make up the difference there was a plan of redemption. Instead of the firstborn of all the nation being given for service to the Lord, an offering of five shekels was given for each one, Numbers 3:44-48 / Numbers 18:16 / 1 Peter 1:18-19.
Matthew Henry, in his commentary, says the following.
‘The number of the first-born, and that of the Levites, came near to each other. Known unto God are all his works beforehand, there is an exact proportion between them, and so it will appear when they are compared together. The small number of first-born, over and above the number of the Levites, were to be redeemed, and the redemption money given to Aaron.’
Moses collected the redemption money from those who exceeded the number redeemed by the Levites and from the firstborn of the Israelites he collected silver weighing 1,365 shekels, according to the sanctuary shekel, Numbers 3:49-50 / Numbers 18:16. Moses then gives the redemption money to Aaron and his sons, as he was commanded, Numbers 3:51.
