Leviticus 7:32

30With his own hands he shall bring the offerings of the LORD made by fire. He shall bring the fat with the breast, that the breast may be waved for a wave offering before the LORD.

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

32The right thigh you shall give to the priest for a heave offering out of the sacrifices of your peace offerings.

33He among the sons of Aaron who offers the blood of the peace offerings, and the fat, shall have the right thigh for a portion.

34For the waved breast and the heaved thigh I have taken from the children of Israel out of the sacrifices of their peace offerings, and have given them to Aaron the priest and to his sons as their portion forever from the children of Israel.’”
