Leviticus 16:10-11

Leeser(i) 10 But the goat on which fell the lot “for ‘Azazel,” shall be placed alive before the Lord, to make an atonement with him, by sending him away to ‘Azazel into the wilderness. 11 And Aaron shall bring near the bullock of the sin-offering, which is for himself, and he shall make an atonement for himself, and for his house; and he shall kill the bullock of the sin-offering which is for himself.
