Exodus 29:19-28
The ram of ordination consecrates Aaron and His sons with blood, oil, and offerings so they may serve as priests before the Lord.
19 “You shall take the other ram, and Aaron and his sons shall lay their hands on the head of the ram.
20 Then you shall kill the ram, and take some of its blood, and put it on the tip of the right ear of Aaron, and on the tip of the right ear of his sons, and on the thumb of their right hand, and on the big toe of their right foot; and sprinkle the blood around on the altar.
21 You shall take of the blood that is on the altar, and of the anointing oil, and sprinkle it on Aaron, and on his garments, and on his sons, and on the garments of his sons with him: and he shall be made holy, and his garments, and his sons, and his sons’ garments with him.
22 Also you shall take some of the ram’s fat, the fat tail, the fat that covers the innards, the cover of the liver, the two kidneys, the fat that is on them, and the right thigh (for it is a ram of consecration),
23 and one loaf of bread, one cake of oiled bread, and one wafer out of the basket of unleavened bread that is before Yahweh.
24 You shall put all of this in Aaron’s hands, and in his sons’ hands, and shall wave them for a wave offering before Yahweh.
25 You shall take them from their hands, and burn them on the altar on the burnt offering, for a pleasant aroma before Yahweh: it is an offering made by fire to Yahweh.
26 “You shall take the breast of Aaron’s ram of consecration, and wave it for a wave offering before Yahweh. It shall be your portion.
27 You shall sanctify the breast of the wave offering and the thigh of the wave offering, which is waved, and which is raised up, of the ram of consecration, even of that which is for Aaron, and of that which is for his sons.
28 It shall be for Aaron and his sons as their portion forever from the children of Israel; for it is a wave offering. It shall be a wave offering from the children of Israel of the sacrifices of their peace offerings, even their wave offering to Yahweh.
The ram of ordination consecrates Aaron and his sons with blood, oil, and offerings so they may serve as priests before the LORD.
To command the second ram of ordination, including hand-laying, blood applied to Aaron and his sons, blood splashed on the altar, blood and oil sprinkled on priests and garments, the wave offering placed in priestly hands, and the priestly portions established as a lasting due from Israel’s fellowship offerings.
This unit follows the bull sin offering and the first ram burnt offering in the consecration sequence. The earlier offerings dealt with purification and whole-offering dedication; this passage moves to the ram of ordination, where Aaron and his sons themselves are visibly marked and installed for priestly service. It also anticipates the ongoing priestly portions that will belong to Aaron and his sons from Israel's fellowship offerings.
The second ram follows the bull of the sin offering and the first ram as burnt offering. This ram is specifically the ram of ordination, focusing on the installation of Aaron and his sons into priestly office.
The Consecration of the Priests and the LORD’s Promise to Dwell Among Israel
The LORD consecrates priests, altar, and daily sacrifice so He may meet with Israel, dwell among them, and be known as the God who redeemed them from Egypt.
