Exodus 29:26

23 and one loaf of bread, one cake of oiled bread, and one wafer out of the basket of unleavened bread that is before the LORD.

24 You 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.

25 You 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.

27 You 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.

28 It 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.

29 “The holy garments of Aaron shall be for his sons after him, to be anointed in them, and to be consecrated in them.
