Judges 11:19-22

19Israel sent messengers to King Sihon, the Amorite king who ruled in Heshbon, and said to him, “Please allow us to pass through your land to our land.”

20But Sihon did not trust Israel to pass through his territory. He assembled his whole army, camped in Jahaz, and fought with Israel.

21The Lord God of Israel handed Sihon and his whole army over to Israel and they defeated them. Israel took all the land of the Amorites who lived in that land.

22They took all the Amorite territory from the Arnon River on the south to the Jabbok River on the north, from the desert in the east to the Jordan in the west.
