Exodus 29:5-9

5And thou shalt take the garments, and clothe Aaron with the vest, and the cloak of the ephod, and the ephod, and the breastplate, and shalt gird him with the girdle of the ephod.

6And thou shalt put the turban upon his head, and fasten the holy diadem to the turban,

7and shalt take the anointing oil, and pour [it] on his head, and anoint him.

8And thou shalt bring his sons near, and clothe them with the vests.

9And thou shalt gird them with the girdle — Aaron and his sons, and bind the high caps on them; and the priesthood shall be theirs for an everlasting statute; and thou shalt consecrate Aaron and his sons.
