Leviticus 8:12-14

Amplified Bible

¹² Then he poured some of the anointing oil on Aaron’s head and anointed him, to consecrate him. ¹³ Next Moses brought Aaron’s sons forward, put undertunics on them, belted them with sashes, and bound caps on them, just as the Lord had commanded Moses.

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