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.
