Leviticus 6:17-18

171It shall not be baked with leaven. I have given it as their share from My offerings by fire; 2it is most holy, like the sin offering and 3the guilt offering. 184Every male among the sons of Aaron may eat it; it is a permanent ordinance throughout your generations, from the offerings by fire to the Lord. 56Whoever touches them 7will become consecrated.’”
