Leviticus 7:29-31

7:29 “Tell the Israelites, ‘The one who presents his peace offering sacrifice to the Lord must bring his offering to the Lord from his peace offering sacrifice. 7:30 With his own hands he must bring the Lord’s gifts. He must bring the fat with the breast to wave the breast as a wave offering before the Lord, 7:31 and the priest must offer the fat up in smoke on the altar, but the breast will belong to Aaron and his sons.
