Exodus 29:8-11

8Bring Aaron's sons and dress them in their special shirts.

9Put the cloth hats on their heads. Tie the long cloth belts around Aaron and on his sons. These men and their descendants will always be priests. That is a law that continues for ever. That is how you must make Aaron and his sons God's special servants.

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

11Then kill the animal as an offering to the Lord, at the entrance of the Tent of Meeting.
