Exodus 29:5-9

5Then take the garments and clothe Aaron with the tunic, the robe for the ephod, the ephod itself, and the breastpiece; fasten the ephod on him with its woven waistband.

6Put the turban on his head and place the holy diadem on the turban.

7Take the anointing oil, pour it on his head, and anoint him.

8You must also bring his sons and clothe them with tunics.

9Tie the sashes on Aaron and his sons and fasten headbands on them. The priesthood is to be theirs by a permanent statute. This is the way you will ordain Aaron and his sons.
