Numbers 21:33-35

33And they turned and went up by the way to Bashan. So Og king of Bashan went out against them, he and all his people, to battle at Edrei.

34Then the Lord said to Moses, “Do not fear him, for I have delivered him into your hand, with all his people and his land; and you shall do to him as you did to Sihon king of the Amorites, who dwelt at Heshbon.”

35So they defeated him, his sons, and all his people, until there was no survivor left him; and they took possession of his land.
