Numbers 21:21-24

21The Israelites sent men with a message to Sihon, the king of the Amorites.

22They said, ‘Please let us travel through your country. We will not go through any fields or through any vineyards. We will not even drink water from your wells. We will go along the main road. We will not leave that road on either side until we have gone through all your land.’

23But Sihon would not let the Israelites travel through his land. Sihon and his army marched to Jahaz, in the desert. They attacked the Israelites there.

24The Israelites fought against the army of Sihon and they won. They got power over the land from the River Arnon to the River Jabbok. But the border of the Ammonites' land had strong towns, so they could not go beyond them.
