Leviticus 4:8-10

Christian Standard Bible

⁸ He is to remove all the fat from the bull of the sin offering: the fat surrounding the entrails, all the fat that is on the entrails, ⁹ and the two kidneys with the fat on them at the loins. He will also remove the fatty lobe of the liver with the kidneys, ¹⁰ just as the fat is removed from the ox of the fellowship sacrifice.^(A) The priest is to burn them on the altar of burnt offering.
