Numbers 3

Numbers 3:1-51 . THE LEVITES' SERVICE.

1. These . . . are the generations of Aaron and Moses, &c.--This chapter contains an account of their families; and although that of Moses is not detailed like his brother's, his children are included under the general designation of the Amramites ( Numbers 3:27 ), a term which comprehends all the descendants of their common father Amram. The reason why the family of Moses was so undistinguished in this record is that they were in the private ranks of the Levites, the dignity of the priesthood being conferred exclusively on the posterity of Aaron; and hence, as the sacerdotal order is the subject of this chapter, Aaron, contrary to the usual style of the sacred history, is mentioned before Moses.
in the day that the Lord spake with Moses in mount Sinai--This is added, because at the date of the following record the family of Aaron was unbroken.

2-4. And these are the names of the sons of Aaron--All the sons of Aaron, four in number, were consecrated to minister in the priest's office. The two oldest enjoyed but a brief term of office ( Leviticus 10:1 Leviticus 10:2 , Numbers 3:4 , 26:61 ); but Eleazar and Ithamar, the other two, were dutiful, and performed the sacred service during the lifetime of their father, as his assistants, and under his superintendence.

5-10. Bring the tribe of Levi near--The Hebrew word "bring near" is a sacrificial term, denoting the presentation of an offering to God; and the use of the word, therefore, in connection with the Levites, signifies that they were devoted as an offering to the sanctuary, no longer to be employed in any common offices. They were subordinate to the priests, who alone enjoyed the privilege of entering the holy place; but they were employed in discharging many of the humbler duties which belonged to the sanctuary, as well as in various offices of great utility and importance to the religion and morals of the people.

9. they are wholly given unto him out of the children of Israel, &c.--The priests hold the place of God, and the Levites are the servants of God in the obedience they render to the priests.

11-13. I have taken the Levites, &c.--The consecration of this tribe did not originate in the legislative wisdom of Moses, but in the special appointment of God, who chose them as substitutes for the first-born. By an appointment made in memory of the last solemn judgment on Egypt (from which the Israelitish households were miraculously exempt) all the first-born were consecrated to God ( Exodus 13:12 , 22:29 ), who thus, under peculiar circumstances, seemed to adopt the patriarchal usage of appointing the oldest to act as the priest of the family. But the privilege of redemption that was allowed the first-born opened the way for a change; and accordingly, on the full organization of the Mosaic economy, the administration of sacred things formerly committed to the first-born was transferred from them to the Levites, who received that honor partly as a tribute to Moses and Aaron, partly because this tribe had distinguished themselves by their zeal in the affair of the golden calf ( Exodus 32:29 ), and also because, being the smallest of the tribes, they could ill find suitable employment and support in the The designation of a special class for the sacred offices of religion was a wise arrangement; for, on their settlement in Canaan, the people would be so occupied that they might not be at leisure to wait on the service of the sanctuary, and sacred things might, from various causes, fall into neglect. But the appointment of an entire tribe to the divine service ensured the regular performance of the rites of religion. The subsequent portion of the chapter relates to the formal substitution of this tribe.
I am the Lord--that is, I decree it to be so; and being possessed of sovereign authority, I expect full obedience.
