Exodus 29:22-24

22“From this ⌞same⌟ ram take the fat, the fat from the tail, the fat that covers the internal organs, the lobe of the liver, the two kidneys with the fat on them, and the right thigh. (This is the ram for the ordination.)

23From the basket of unleavened bread which is in the Lord’s presence, take a round loaf of bread, a ring of bread made with olive oil, and a wafer.

24Put all of these in the hands of Aaron and his sons, who will offer them to the Lord.
