Exodus 29:26-28

Young's Literal Translation

²⁶ `And thou hast taken the breast from the ram of the consecration which [is] for Aaron, and hast waved it -- a wave-offering before Jehovah, and it hath become thy portion;

²⁷ and thou hast sanctified the breast of the wave-offering, and the leg of the heave-offering, which hath been waved, and which hath been lifted up from the ram of the consecration, of that which [is] for Aaron, and of that which [is] for his sons;

²⁸ and it hath been for Aaron and for his sons, by a statute age-during from the sons of Israel, for it [is] a heave-offering; and it is a heave offering from the sons of Israel, from the sacrifices of their peace-offerings -- their heave-offering to Jehovah.
