Exodus 29:12-14

Revised Standard Version Catholic Edition

¹² and shall take part of the blood of the bull and put it upon the horns of the altar with your finger, and the rest of^[a] the blood you shall pour out at the base of the altar. ¹³ And 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 burn them upon 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.
