Exodus 29:4-9

4You are to bring Aaron and his sons to the entrance of the Tent of Meeting, and wash them with water.

5Then take the garments, and put the tunic on Aaron, along with the robe, the ephod and the breastplate. Gird him with the artfully woven band of the ephod,

6set the turban on his head, and put the holy coronet on the turban.

7Then you are to take the anointing oil, pour it upon his head and anoint him.

8Also you are to bring his sons and put tunics on them.

9You are to gird Aaron and his sons with sashes, tie headwear on them, and they shall hold the priesthood by a perpetual statute. In this way you are to consecrate Aaron and his sons.
