Deuteronomy 2:36

31 And the Lord said to me, See, from now on I have given Sihon and his land into your hands: go forward now to take his land and make it yours.

32 Then Sihon came out against us with all his people, to make an attack on us at Jahaz.

33 And the Lord our God gave him into our hands; and we overcame him and his sons and all his people.

34 At that time we took all his towns, and gave them over to complete destruction, together with men, women, and children; we had no mercy on any:

35 Only the cattle we took for ourselves, with the goods from the towns we had taken.

36 From Aroer on the edge of the valley of the Arnon and from the town in the valley as far as Gilead, no town was strong enough to keep us out; the Lord our God gave them all into our hands:

37 But you did not go near the land of the children of Ammon, that is, all the side of the river Jabbok or the towns of the hill-country, wherever the Lord our God had said we were not to go.
