Exodus 29:24-26

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.
