Numbers 21:30-34

“But we have shot them down with arrows, Heshbon is destroyed as far as Dibon, Then we have laid waste as far as Nophah, Which reaches to Medeba.”

So Israel lived in the land of the Amorites.

Now Moses sent men 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 of Bashan, and Og the king of Bashan went out against them with all his people, for battle at Edrei.

But the Lord said to Moses, “Do not fear him, for I have handed him over to you, and all his people and his land; and you shall do to him as you did to Sihon, king of the Amorites, who lived in Heshbon.”
