Numbers 21:21-25

21Israel sent messengers to King Sihon of the Amorites saying,

22“Permit us to pass through your land. We will not turn aside into field or vineyard nor drink water from the wells. We will travel on the king’s highway until we will have passed through your territory.”

23But Sihon would not let Israel pass through his territory. Instead, Sihon called out his entire army and marched out into the desert to oppose Israel. When he came to Jahaz, he fought against Israel.

24But Israel struck him by the sword’s edge and conquered his land from Arnon to Jabbok as far as the Ammonites, because the border of the sons of Ammon was fortified.

25Israel conquered all these cities and occupied all the Amorite cities, Heshbon and all its towns.
