13and put on Aaron the holy garments. And you shall anoint him and consecrate him, that he may serve me as priest. 14You shall bring his sons also and put coats on them, 15 aand anoint them, as you anointed their father, that they may serve me as priests. And their anointing shall admit them to a bperpetual priesthood throughout their generations.”
