Exodus 40:13-15

New Revised Standard Version Catholic Edition

¹³ and put on Aaron the sacred vestments, and you shall anoint him and consecrate him, so that he may serve me as priest. ¹⁴ You shall bring his sons also and put tunics on them, ¹⁵ and anoint them, as you anointed their father, that they may serve me as priests: and their anointing shall admit them to a perpetual priesthood throughout all generations to come.
