Exodus 40:14-16

King James Version

¹⁴ And thou shalt bring his sons, and clothe them with coats:

¹⁵ And thou shalt anoint them, as thou didst anoint their father, that they may minister unto me in the priest's office: for their anointing shall surely be an everlasting priesthood throughout their generations.

¹⁶ Thus did Moses: according to all that the Lord commanded him, so did he.
