Exodus 29:25

22 Also thou shalt take of the ram the fat and the rump, and the fat that covereth the inwards, and the caul [above] the liver, and the two kidneys, and the fat that [is] upon them, and the right shoulder; for it [is] a ram of consecration:

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

24 And thou shalt put all in the hands of Aaron, and in the hands of his sons; and shalt wave them [for] a wave-offering before the LORD.

25 And thou shalt receive them from their hands, and burn [them] upon the altar for a burnt-offering, for a sweet savor before the LORD: it [is] an offering made by fire to the LORD.

26 And thou shalt take the breast of the ram of Aaron's consecration, and wave it [for] a wave-offering before the LORD: and it shall be thy part.

27 And thou shalt sanctify the breast of the wave-offering, and the shoulder of the heave-offering, which is waved, and which is heaved up of the ram of the consecration, [even] of [that] which [is] for Aaron, and of [that] which is for his sons:

28 And it shall be Aaron's and his sons' by a statute 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 sacrifice of their peace-offerings, [even] their heave-offering to the LORD.
