2. Mose 29:19

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.).

29:19-28 This ordination offering is very similar to the peace (or fellowship) offering later described in Lev 3. The fat was burned as a gift to the Lord, but the breast and the thigh, after having been dedicated to the Lord by lifting them up before him (29:24-26), became the portion for the priests to eat (29:26-28). In the regular peace offering, the remainder of the meat was to be eaten by the person making the offering in a fellowship meal (Lev 7:11-18), as the priests did here (Exod 29:31-34).
