Exodus 29:6

2And unleavened bread, and cakes unleavened tempered with oil, and wafers unleavened anointed with oil: of wheaten flour shalt thou make them.

3And thou shalt put them into one basket, and bring them in the basket, with the bullock and the two rams.

4And Aaron and his sons thou shalt bring unto the door of the tabernacle of the congregation, and shalt wash them with water.

5And thou shalt take the garments, and put upon Aaron the coat, and the robe of the ephod, and the ephod, and the breastplate, and gird him with the curious girdle of the ephod:

6And thou shalt put the mitre upon his head, and put the holy crown upon the mitre.

7Then shalt thou take the anointing oil, and pour it upon his head, and anoint him.

8And thou shalt bring his sons, and put coats upon them.

9And thou shalt gird them with girdles, Aaron and his sons, and put the bonnets on them: and the priest’s office shall be theirs for a perpetual statute: and thou shalt consecrate Aaron and his sons.

10And thou shalt cause a bullock to be brought before the tabernacle of the congregation: and Aaron and his sons shall put their hands upon the head of the bullock.
