Exodus 29:24-26

24and thou shalt put all this in the hands of Aaron, and in the hands of his sons, and shalt wave them as a wave-offering before Jehovah.

25And thou shalt receive them of their hand and burn [them] upon the altar over the burnt-offering, for a sweet odour before Jehovah: it is an offering by fire to Jehovah.

26And thou shalt take the breast of the ram of consecration which is for Aaron, and wave it as a wave-offering before Jehovah; and it shall be thy part.
