Leviticus 8:26-27

²⁶Out of the basket of bread without yeast that was before Yahweh, he took one loaf without yeast, and one loaf of oiled bread, and one wafer, and placed them on the fat and on the right thigh.

²⁷He put it all in the hands of Aaron and in the hands of his sons and waved them before Yahweh as a wave offering.
