Exodus 29:6

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

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

5 And 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 skilfully woven band of the ephod;

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

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

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

9 And thou shalt gird them with girdles, Aaron and his sons, and bind head-tires on them: and they shall have the priesthood by a perpetual statute: and thou shalt consecrate Aaron and his sons.
