Exodus 29:7 KJV

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.
