Numbers 21
21 Ref And Israel sent men to Sihon, king of the Amorites, saying,
22 Ref Let me go through your land: we will not go into field or vine-garden, or take the water of the springs; we will go by the highway till we have gone past the limits of your land.
23 Ref And Sihon would not let Israel go through his land; but got all his people together and went out against Israel into the waste land, as far as Jahaz, to make war on Israel.
24 Ref But Israel overcame him, and took all his land from the Arnon to the Jabbok, as far as the country of the children of Ammon, for the country of the children of Ammon was strongly armed.
