Leviticus 4:5

1 Then the LORD said to Moses,

2 “Tell the Israelites to do as follows with one who sins unintentionally against any of the LORD’s commandments and does what is forbidden by them:

3 If the anointed priest sins, bringing guilt on the people, he must bring to the LORD a young bull without blemish as a sin offering for the sin he has committed.

4 He must bring the bull to the entrance to the Tent of Meeting before the LORD, lay his hand on the bull’s head, and slaughter it before the LORD.

5 Then the anointed priest shall take some of the bull’s blood and bring it into the Tent of Meeting.

6 The priest is to dip his finger in the blood and sprinkle some of it seven times before the LORD, in front of the veil of the sanctuary.

7 The priest must then put some of the blood on the horns of the altar of fragrant incense that is before the LORD in the Tent of Meeting. And he is to pour out the rest of the bull’s blood at the base of the altar of burnt offering at the entrance to the Tent of Meeting.

8 Then he shall remove all the fat from the bull of the sin offering—the fat that covers the entrails, all the fat that is on them,

9 both kidneys with the fat on them near the loins, and the lobe of the liver, which he is to remove with the kidneys—
