Deuteronomy 2:31-35

And the Lord said to me, ‘See, I have begun to turn Sihon and his land over to you. Begin taking possession, so that you may possess his land.’

“Then Sihon came out with all his people to meet us in battle at Jahaz.

And the Lord our God turned him over to us, and we defeated him with his sons and all his people.

So we captured all his cities at that time and utterly destroyed the men, women, and children of every city. We left no survivor.

We took only the animals as our plunder, and the spoils of the cities which we had captured.
