6He must dip one of his fingers into the blood and sprinkle it seven times in the presence of Yahweh, in front of the curtain that separates the Holy Place from the Very Holy Place.
7Then he must put some of the blood on the projections at the corners of the altar where fragrant incense is burned in the Sacred Tent in the presence of Yahweh. The remaining part of the bull's blood that is still in the bowl, he must pour out at the base of the altar, where sacrifices are burned, at the entrance to the Sacred Tent.
8From that offering the Supreme Priest must separate these things from the bull that is to be burned: The fat that covers the inner parts of the bull or which is attached to them—
9the kidneys and the fat that is attached to them near the lower back muscle, and the fat that covers the liver.
10Then the Supreme Priest must completely burn those things on the altar. That will be just like when the fat is removed from an animal that is sacrificed to maintain good fellowship with Yahweh.
