Leviticus 7:31-34 The priest is to burn the fat on the altar, but the breast belongs to Aaron and his sons.

BSB⁽ⁱ⁾ ³¹ The priest is to burn the fat on the altar, but the breast belongs to Aaron and his sons. ³² And you are to give the right thigh to the priest as a contribution from your peace offering. ³³ The son of Aaron who presents the blood and fat of the peace offering shall have the right thigh as a portion. ³⁴ I have taken from the sons of Israel the breast of the wave offering and the thigh of the contribution of their peace offerings, and I have given them to Aaron the priest and his sons as a permanent portion from the sons of Israel.’”
