Leviticus 7:30-32

³⁰his own hands shall bring the oblations of the Lord: let him bring the fat with the breast, that the breast may be lifted up an uplifting before the Lord.

³¹And the priest shall burn the fat at the altar; but the breast shall be for Aharon and his sons.

³²And the right shoulder (also) of your sanctified victims you shall give for a separation unto the priest.
