Exodus 29:24-26

24Put all these things in the hands of Aaron and his sons. Then lift these things up to the Lord as an offering to him.

25Then take them from Aaron and his sons and burn them on the altar. It is a burnt offering to the Lord. Its smell pleases him.

26Take the meat from the ribs of the sheep that makes Aaron God's special servant. Lift it up to the Lord as an offering to him. Then you may eat this meat from the sheep.
