Judges 11:19-22

19Then Israel sent messengers to Sihon king of the Amorites, king of Heshbon; and Israel said to him, “Please let us pass through your land into our place.”

20But Sihon did not trust Israel to pass through his territory. So Sihon gathered all his people together, encamped in Jahaz, and fought against Israel.

21And the Lord God of Israel delivered Sihon and all his people into the hand of Israel, and they defeated them. Thus Israel gained possession of all the land of the Amorites, who inhabited that country.

22They took possession of all the territory of the Amorites, from the Arnon to the Jabbok and from the wilderness to the Jordan.
