Исход 29:10

Consecration of Aaron and his Sons through the anointing of their persons and the offering of sacrifices, the directions for which form the subject of vv. 1-35. This can only be fully understood in connection with the sacrificial law contained in Lev 1-7. It will be more advisable therefore to defer the examination of this ceremony till we come to Lev 8, where the consecration itself is described. The same may also be said of the expiation and anointing of the altar, which are commanded in Exo 29:36 and Exo 29:37, and carried out in Lev 8:11.

Particular orders are given in this chapter, I. Concerning the consecration of the priests, and the sanctification of the altar (v. 1-37). II. Concerning the daily sacrifice (Exo 29:38-41). To which gracious promises are annexed that God would own and bless them in all their services (Exo 29:42, etc.).

29:10-34 The consecration of the priesthood of Aaron involved a sin offering (29:10-14), a burnt offering (29:15-18), and an ordination offering (29:19-28). The same patterns established here are expanded to the regular offerings of the people (see 29:38-46; Lev 1–5). In all three cases, Aaron and his sons lay their hands on [the] head of the sacrificial animals (Exod 29:10, 15, 19), indicating that sin is a matter of life and death, and that it can only be removed by a death. Because it represents life, blood is prominent in these ceremonies (29:12, 16, 20, 21).
