Leviticus 9:19-21

Amplified Bible

¹⁹ As for the portions of fat from the bull and from the ram—the fat tail, and the fat covering the internal organs, and the kidneys, and the lobe of the liver— ²⁰ they now put the portions of fat on the breasts; and Aaron offered the fat up in smoke on the altar. ²¹ But the breasts and the right thigh Aaron presented as a wave offering before the Lord, just as Moses had commanded.
