Numbers 21:31-35 ESV
Thus Israel lived in the land of the Amorites. And Moses sent to spy out Jazer, and they captured its villages and dispossessed the Amorites who were there. Then they turned and went up by the way to Bashan. And Og the king of Bashan came out against them, he and all his people, to battle at Edrei. But the LORD said to Moses, “Do not fear him, for I have given him into your hand, and all his people, and his land. And you shall do to him as you did to Sihon king of the Amorites, who lived at Heshbon.” So they defeated him and his sons and all his people, until he had no survivor left. And they possessed his land.
