Leviticus 4:23; Leviticus 4:18

23 and the sin he has committed becomes known, he must bring as his offering a male goat without defect.

18 He is to put some of the blood on the horns of the altar that is before the LORD in the tent of meeting. The rest of the blood he shall pour out at the base of the altar of burnt offering at the entrance to the tent of meeting.
