Exodus 29:24-26

Lexham English Bible

²⁴ you will put them all on the palms of Aaron and on the palms of his sons, and you will wave them as a wave offering before Yahweh. ²⁵ And you will take them from their hand and turn them to smoke on the altar beside the burnt offering as a fragrance of appeasement before Yahweh; it is an offering made by fire before Yahweh.

²⁶ “And you will take the breast section from the ram of ordination that is for Aaron, and you will wave it as a wave offering before Yahweh. It will be your portion.
