Judges 11:18-21

“Then they journeyed through the wilderness and went around the land of Edom and the land of Moab and arrived on the east side of the land of Moab and camped on the other side of the Arnon. But they did not enter the territory of Moab, for the Arnon was the boundary of Moab. Israel 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,’ but 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. And 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.
