Leviticus 7:29-34 Catholic Public Domain Version (CPDV)

29. Speak to the sons of Israel, saying: Whoever offers a victim of peace offerings to the Lord, let him also offer at the same time a sacrifice, that is, its libations.

30. He shall hold in his hands the fat of the victim, and the breast. And when he will have offered and consecrated both to the Lord, he shall deliver them to the priest,

31. who shall burn the fat upon the altar. But the breast shall be for Aaron and his sons.

32. Likewise also, the right shoulder of the victim of peace offerings shall fall to the priest as first-fruits.

33. Among the sons of Aaron, whoever will have offered the blood and the fat, the same one shall also have the right shoulder for his portion.

34. So then, the breast that is lifted up, and the shoulder that is separated, I have taken from the sons of Israel, from their victims of peace offerings, and I have given these to Aaron the priest and to his sons, as a law in perpetuity, from all the people of Israel.
