Exodus 29:24-28

24and thou shalt put the whole upon the hands of Aaron, and upon the hands of his sons, and shalt wave them for a wave-offering before Jehovah. 25And thou shalt take them from their hands, and burn them on the altar upon the burnt-offering, for a sweet savor before Jehovah: it is an offering made by fire unto Jehovah.

26And thou shalt take the breast of Aaron’s ram of consecration, and wave it for a wave-offering before Jehovah: and it shall be thy portion. 27And thou shalt sanctify the breast of the wave-offering, and the thigh of the heave-offering, which is waved, and which is heaved up, of the ram of consecration, even of that which is for Aaron, and of that which is for his sons: 28and it shall be for Aaron and his sons as their portion for ever from the children of Israel; for it is a heave-offering: and it shall be a heave-offering from the children of Israel of the sacrifices of their peace-offerings, even their heave-offering unto Jehovah.
