Leviticus 7:33

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

31 And the priest shall burn the fat upon the altar; but the breast shall be Aaron`s and his sons`.

32 And the right thigh shall ye give unto the priest for a heave-offering out of the sacrifices of your peace-offerings.

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

34 For the wave-breast and the heave-thigh have I taken of the children of Israel out of the sacrifices of their peace-offerings, and have given them unto Aaron the priest and unto his sons as [their] portion for ever from the children of Israel.

35 This is the anointing-portion of Aaron, and the anointing-portion of his sons, out of the offerings of Jehovah made by fire, in the day when he presented them to minister unto Jehovah in the priest`s office;

36 which Jehovah commanded to be given them of the children of Israel, in the day that he anointed them. It is [their] portion for ever throughout their generations.
