Leviticus 7:30-32

Amplified Bible

³⁰ With his own hands he is to bring offerings by fire to the Lord; he shall bring the fat with the breast, so that the breast may be presented as a wave offering before the Lord. ³¹ The priest shall offer up the fat in smoke on the altar, but the breast shall be for Aaron and his sons. ³² You shall give the right thigh to the priest as a contribution from the sacrifices of your peace offerings.
