Exodus 29:11-13

Living Bible

¹¹ and you shall kill it before the Lord, at the entrance of the Tabernacle. ¹² Place its blood upon the horns of the altar, smearing it on with your finger, and pour the rest at the base of the altar. ¹³ Then take all the fat that covers the inner parts, also the gall bladder and two kidneys, and the fat on them, and burn them upon the altar.
