Exodus 29:4-7

4And Aaron and his sons thou shalt bring unto the door of the tent of meeting, 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 skilfully woven band of the ephod;

6and thou shalt set 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.
