Exodus 29:8-10

New Century Version

⁸ “Then bring his sons and put the inner robes on them. ⁹ Put the headbands on their heads, and tie cloth belts around their waists. Aaron and his descendants will be priests in Israel, according to a rule that will continue from now on. This is how you will appoint Aaron and his sons as priests.

¹⁰ “Bring the bull to the front of the Meeting Tent, and Aaron and his sons must put their hands on the bull’s head.
