Exodus 29:5-9

5Then you shall take the garments, and put on Aaron the coat and the robe of the ephod, and the ephod, and the breastpiece, and gird him with the skillfully woven band of the ephod.

6And you shall set the turban on his head and put the holy crown on the turban.

7You shall take the anointing oil and pour it on his head and anoint him.

8Then you shall bring his sons and put coats on them,

9and you shall gird Aaron and his sons with sashes and bind caps on them. And the priesthood shall be theirs by a statute forever. Thus you shall ordain Aaron and his sons.
