Leviticus 7:30

27 Whoever takes any blood for food will be cut off from his people.

28 And the Lord said to Moses,

29 Say to the children of Israel: He who makes a peace-offering to the Lord, is to give an offering to the Lord out of his peace-offering:

30 He himself is to take to the Lord the offering made by fire, even the fat with the breast, so that the breast may be waved for a wave offering before the Lord.

31 And the fat is to be burned by the priest on the altar, but the breast is for Aaron and his sons.

32 And the right leg you are to give to the priest for an offering to be lifted up out of what is given for your peace-offerings.

33 That man, among the sons of Aaron, by whom the blood of the peace-offering and the fat are offered, is to have the right leg for his part.
