He must then pour the rest of the bull’s blood at the base of the altar of burnt offering located near the entrance of the congregation tent. ⁸ The priest must remove all of the fat from the bull being offered as a purification offering for sin, the fat covering and surrounding the organs, ⁹ the two kidneys and the fat on them near the loins, and the lobe of the liver (which must be removed with the kidneys).
