Leviticus 9:19-21

New King James Version

¹⁹ and the fat from the bull and the ram—the fatty tail, what covers the entrails and the kidneys, and the fatty lobe attached to the liver; ²⁰ and they put the fat on the breasts. ^(A)Then he burned the fat on the altar; ²¹ but the breasts and the right thigh Aaron waved ^(B)as a wave offering before the Lord, as Moses had commanded.
