Judges 11:19-22

19Israel then sent messengers to Sihon king of the Amorites, king of Heshbon, and Israel said to him, 'Please let us pass through your land to our country,'

20but Sihon did not trust Israel to pass through his territory, so Sihon gathered all his people together and encamped at Jahaz and fought with Israel.

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

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