Exodus 40:12-15

12 “Bring Aaron and his sons to the entrance to the tent of meeting and wash them with water.
13 Then dress Aaron in the sacred garments, anoint him and consecrate him so he may serve me as priest.
14 Bring his sons and dress them in tunics.
15 Anoint them just as you anointed their father, so they may serve me as priests. Their anointing will be to a priesthood that will continue throughout their generations.”
