Exodus 29:10-15

10“Then bring the young bull to the front of the tent of meeting. Aaron and his sons will place their hands on its head.

11Slaughter the bull in the Lord’s presence at the entrance to the tent of meeting.

12Take some of the bull’s blood, and put it on the horns of the altar with your finger. Pour the rest of it out at the bottom of the altar.

13“Then take all the fat that covers the internal organs, the lobe of the liver, and the two kidneys with the fat on them, and burn them on the altar.

14But burn the bull’s meat, skin, and excrement outside the camp. It is an offering for sin.

15“Take one of the rams. Then Aaron and his sons will place their hands on its head.
