Leviticus 4:8-10

4:8 “‘Then he must take up all the fat from the sin offering bull: the fat covering the entrails and all the fat surrounding the entrails, 4:9 the two kidneys with the fat on their sinews, and the protruding lobe on the liver (which he is to remove along with the kidneys) 4:10 – just as it is taken from the ox of the peace offering sacrifice – and the priest must offer them up in smoke on the altar of burnt offering.
