Amplified Bible

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.” ¹⁶ Thus Moses did; in accordance with all that the Lord commanded him, so he did.
