Leviticus 7:30-34

30His own hands will bring the food offerings to the Lord. He will bring the fat together with the breast. The breast is to be presented as a presentation offering before the Lord.

31The priest is to burn the fat on the altar, but the breast belongs to Aaron and his sons.

32You are to give the right thigh to the priest as a contribution from your fellowship sacrifices.

33The son of Aaron who presents the blood of the fellowship offering and the fat will have the right thigh as a portion.

34I have taken from the Israelites the breast of the presentation offering and the thigh of the contribution from their fellowship sacrifices, and have assigned them to the priest Aaron and to his sons as a permanent portion from the Israelites.”
