Exodus 29:11-13 New Living Translation (NLT)

11. Then slaughter the bull in the lord’s presence at the entrance of the Tabernacle.

12. Put some of its blood on the horns of the altar with your finger, and pour out the rest at the base of the altar.

13. Take all the fat around the internal organs, the long lobe of the liver, and the two kidneys and the fat around them, and burn it all on the altar.
