Exodus 29:20-30

20 and you shall slaughter the ram, and take some of its blood and put it on the lobe of Aaron's right ear and on the lobes of the right ears of his sons, and on the thumbs of their right hands, and on the big toes of their right feet, and dash the rest of the blood against all sides of the altar.
21 Then you shall take some of the blood that is on the altar, and some of the anointing oil, and sprinkle it on Aaron and his vestments and on his sons and his sons' vestments with him; then he and his vestments shall be holy, as well as his sons and his sons' vestments.
22 You shall also take the fat of the ram, the fat tail, the fat that covers the entrails, the appendage of the liver, the two kidneys with the fat that is on them, and the right thigh (for it is a ram of ordination),
23 and one loaf of bread, one cake of bread made with oil, and one wafer, out of the basket of unleavened bread that is before the Lord;
24 and you shall place all these on the palms of Aaron and on the palms of his sons, and raise them as an elevation offering before the Lord.
25 Then you shall take them from their hands, and turn them into smoke on the altar on top of the burnt offering of pleasing odor before the Lord; it is an offering by fire to the Lord.
26 You shall take the breast of the ram of Aaron's ordination and raise it as an elevation offering before the Lord; and it shall be your portion.
27 You shall consecrate the breast that was raised as an elevation offering and the thigh that was raised as an elevation offering from the ram of ordination, from that which belonged to Aaron and his sons.
28 These things shall be a perpetual ordinance for Aaron and his sons from the Israelites, for this is an offering; and it shall be an offering by the Israelites from their sacrifice of offerings of well-being, their offering to the Lord.
29 The sacred vestments of Aaron shall be passed on to his sons after him; they shall be anointed in them and ordained in them.
30 The son who is priest in his place shall wear them seven days, when he comes into the tent of meeting to minister in the holy place.

Exodus 29:20-30 Meaning and Commentary

INTRODUCTION TO EXODUS 29

This chapter gives an account of the form and order of the consecration of Aaron and his sons to the priestly office; preparatory to which Moses is ordered to take a young bullock, two rams, bread, cakes, and wafers unleavened, and bring them and Aaron and his sons to the door of the congregation, where the ceremony was to be publicly performed, and which began with washing them, Ex 29:1-4 and then proceeded by putting on the priestly garments directed to be made in the preceding chapter, first on Aaron, who also was anointed, Ex 29:5-7 and then upon his sons, Ex 29:8,9 after which the bullock and the two rams were to be slain, and orders are given what was to be done with their blood, and the several parts of them, as well as with the cakes and wafers, Ex 29:10-23 and directions are given to make these wave and heave offerings, Ex 29:24-28 and that the garments of Aaron's should be his son's that succeeded him, Ex 29:29,30, and that the flesh of the ram of consecration with the bread should be eaten by Aaron and his sons and no other, Ex 29:31-35, the altar also where they were to officiate was to be cleansed, sanctified, and an atonement made for it, Ex 29:36,37 after which two lambs every day, morning and evening, were to be offered on it in all succeeding generations, Ex 29:38-42, and the chapter is closed with a promise that the Lord would meet with the children of Israel at the door of the tabernacle of the congregation, and would sanctify the tabernacle, and dwell among them, and be their God, Ex 29:43-46.
