Leviticus 8:12

10Moses took the anointing oil, and anointed the tabernacle and all that was in it, and sanctified them.

11He sprinkled it on the altar seven times, and anointed the altar and all its vessels, and the basin and its base, to sanctify them.

12He poured some of the anointing oil on Aaron’s head, and anointed him, to sanctify him.

13Moses brought Aaron’s sons, and clothed them with tunics, and tied sashes on them, and put headbands on them, as the LORD commanded Moses.

14He brought the bull of the sin offering, and Aaron and his sons laid their hands on the head of the bull of the sin offering.
