Exodus 40:12-16

40:12 And thou shalt bring Aaron and his sons unto the door of the tabernacle of the congregation, and wash them with water. 40:13 And thou shalt put upon Aaron the holy garments, and anoint him, and sanctify him; that he may minister unto me in the priest’s office. 40:14 And thou shalt bring his sons, and clothe them with coats: 40:15 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. 40:16 Thus did Moses: according to all that the LORD commanded him, so did he.
