Exodus 29:12-14

New Revised Standard Version, Anglicised

¹² and shall take some of the blood of the bull and put it on the horns of the altar with your finger, and all the rest of the blood you shall pour out at the base of the altar. ¹³ You shall take all the fat that covers the entrails, and the appendage of the liver, and the two kidneys with the fat that is on them, and turn them into smoke on the altar. ¹⁴ But the flesh of the bull, and its skin, and its dung, you shall burn with fire outside the camp; it is a sin-offering.
