Exodus 29:11-13

Amplified Bible

¹¹ Then you shall kill the bull before the Lord by the doorway of the Tent of Meeting. ¹² And you shall take some of the blood of the bull and with your finger put it on the horns of the altar [of burnt offering], and you shall pour out the remainder of the blood at the base of the altar. ¹³ You shall take all the fat that covers the intestines and the lobe of the liver, and the two kidneys and the fat that is on them, and offer them up in smoke on the altar.
