Judg 11:18-22

18Then they journeyed through the wilderness, went around the land of Edom and the land of Moab, arrived on the east side of the land of Moab, and camped on the other side of the Arnon. They did not enter the territory of Moab, for the Arnon was the boundary of Moab.19Israel then sent messengers to King Sihon of the Amorites, king of Heshbon; and Israel said to him, ‘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.21Then the Lord, the God of Israel, gave Sihon and all his people into the hand of Israel, and they defeated them; so Israel occupied all the land of the Amorites, who inhabited that country.22They occupied all the territory of the Amorites from the Arnon to the Jabbok and from the wilderness to the Jordan.
