Leviticus 7:36

32 and the right leg ye do make a heave-offering to the priest of the sacrifices of your peace-offerings;

33 he of the sons of Aaron who is bringing near the blood of the peace-offerings, and the fat, his is the right leg for a portion.

34 `For the breast of the wave-offering, and the leg of the heave-offering, I have taken from the sons of Israel, from the sacrifices of their peace-offerings, and I give them to Aaron the priest, and to his sons, by a statute age-during, from the sons of Israel.`

35 This [is] the anointing of Aaron, and the anointing of his sons out of the fire-offerings of Jehovah, in the day he hath brought them near to act as priest to Jehovah,

36 which Jehovah hath commanded to give to them in the day of His anointing them, from the sons of Israel -- a statute age-during to their generations.

37 This [is] the law for burnt-offering, for present, and for sin-offering, and for guilt-offering, and for consecrations, and for a sacrifice of the peace-offerings,

38 which Jehovah hath commanded Moses in Mount Sinai, in the day of his commanding the sons of Israel to bring near their offerings to Jehovah, in the wilderness of Sinai.
