Leviticus 7:29-32

29"Speak to the people of Israel, saying, Whoever offers the sacrifice of his peace offerings to the Lord shall bring his offering to the Lord from the sacrifice of his peace offerings.

30His own hands shall bring the Lord's food offerings. He shall bring the fat with the breast, that the breast may be waved as a wave offering before the Lord.

31The priest shall burn the fat on the altar, but the breast shall be for Aaron and his sons.

32And the right thigh you shall give to the priest as a contribution from the sacrifice of your peace offerings.
