Num 21:33-35

King Og Defeated 33Then they turned and went up the road to Bashan; and King Og of Bashan came out against them, he and all his people, to battle at Edrei.34But the Lord said to Moses, “Do not be afraid of him; for I have given him into your hand, with all his people, and all his land. You shall do to him as you did to King Sihon of the Amorites, who ruled in Heshbon.”35So they killed him, his sons, and all his people, until there was no survivor left; and they took possession of his land.
