Exodus 40:13-15

Amplified Bible

¹³ You shall put the holy garments on Aaron and anoint him and consecrate him, that he may serve as a priest to Me. ¹⁴ You shall bring his sons and put tunics on them; ¹⁵ you shall anoint them just as you anointed their father, so that they may serve as priests to Me; and their anointing shall qualify them for an everlasting priesthood throughout their generations.”
