13. At last, Moses dressed Aaron's sons in their shirts, then tied sashes around them and put special caps on them, just as the Lord had commanded.
14. Moses led out the bull that was to be sacrificed for sin, and Aaron and his sons laid their hands on its head.
15. After it was killed, Moses dipped a finger in the blood and smeared some of it on each of the four corners of the bronze altar, before pouring out the rest at the foot of the altar. This purified the altar and made it a fit place for offering the sacrifice for sin.
16. Moses then took the fat on the bull's insides, as well as the lower part of the liver and the two kidneys with their fat, and sent them up in smoke on the altar fire.
