Exodus 29:11-13

New International Version - UK

¹¹ Slaughter it in the Lord’s presence at the entrance to the tent of meeting. ¹² Take some of the bull’s blood and put it on the horns of the altar with your finger, and pour out the rest of it at the base of the altar. ¹³ Then take all the fat on the internal organs, the covering of the liver, and both kidneys with the fat on them, and burn them on the altar.
