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 the Lord: 24And 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.1 25And thou shalt receive them of their hands, and burn them upon the altar for a burnt offering, for a sweet savour before the Lord: it is an offering made by fire unto the Lord. 26And 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. 27And 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: 28And it shall be Aaron’s and his sons’ by a statute for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifice of their peace offerings, even their heave offering unto the Lord.

29And the holy garments of Aaron shall be his sons’ after him, to be anointed therein, and to be consecrated in them. 30And that son that is priest in his stead shall put them on seven days, when he cometh into the tabernacle of the congregation to minister in the holy place.2
