Exodus 29:23-30

23and one loaf of bread, and one cake of oiled bread, and one wafer out of the basket of the unleavened [bread] that is before Jehovah;

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.

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

28And they shall be for Aaron and his sons, as an everlasting statute, on the part of the children of Israel; for it is a heave-offering; and it shall be a heave-offering on the part of the children of Israel of the sacrifices of their peace-offerings, [as] their heave-offering to Jehovah.

29And the holy garments of Aaron shall be his sons' after him, to be anointed therein, and to be consecrated in them.

30The son that is priest in his stead shall put them on seven days, when he cometh into the tent of meeting to serve in the sanctuary.
