Leviticus 8:26-27

²⁶and out of the basket of unleavened bread, that was before Jehovah, he took one unleavened cake, and one cake of oiled bread, and one wafer, and placed them on the fat, and upon the right thigh:

²⁷and he put the whole upon the hands of Aaron, and upon the hands of his sons, and waved them for a wave-offering before Jehovah.
