Exodus 29:7-9

Amplified Bible, Classic Edition

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

⁸ And bring his sons and put long and sleeved tunics on them.

⁹ And you shall gird them with sashes or belts, Aaron and his sons, and bind caps on them; and the priest’s office shall be theirs by a perpetual statute. Thus you shall ordain and consecrate Aaron and his sons.
