Exodus 29:5-9

5Then you shall take the garments, and put on Aaron the tunic and the robe of the ephod and the ephod and the breastpiece, and wrap him with the skillfully woven sash of the ephod;

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

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

8You shall bring his sons and put tunics on them.

9And you shall wrap them with sashes, Aaron and his sons, and put the [ornamental] caps on them; and the priest’s office shall be theirs by a perpetual statute. So you shall ordain Aaron and his sons.
