Leviticus 8:26-28

²⁶and out of the basket of unleavened bread, that was before the Lord, he took one unleavened cake, and a cake of oiled bread, and one wafer, and put them on the fat, and upon the right shoulder:

²⁷and he put all upon Aaron’s hands, and upon his sons’ hands, and waved them for a wave offering before the Lord.

²⁸And Moses took them from off their hands, and burnt them on the altar upon the burnt offering: they were consecrations for a sweet savour: it is an offering made by fire unto the Lord.
