Exodus 29:26

24You shall put all of this in Aaron’s hands, and in his sons’ hands, and shall wave them for a wave offering before the LORD.

25You shall take them from their hands, and burn them on the altar on the burnt offering, for a pleasant aroma before the LORD: it is an offering made by fire to the LORD.

26“You shall take the breast of Aaron’s ram of consecration, and wave it for a wave offering before the LORD. It shall be your portion.

27You shall sanctify the breast of the wave offering and the thigh of the wave offering, which is waved, and which is raised up, of the ram of consecration, even of that which is for Aaron, and of that which is for his sons.

28It shall be for Aaron and his sons as their portion forever from the children of Israel; for it is a wave offering. It shall be a wave offering from the children of Israel of the sacrifices of their peace offerings, even their wave offering to the LORD.
