Numbers 21:23 WEB

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

²²  Let me pass through your land: we will not turn aside into field, or into vineyard; we will not drink of the water of the wells: we will go by the king's highway, until we have passed your border.

²³  Sihon would not allow Israel to pass through his border: but Sihon gathered all his people together, and went out against Israel into the wilderness, and came to Jahaz; and he fought against Israel.

²⁴  Israel struck him with the edge of the sword, and possessed his land from the Arnon to the Jabbok, even to the children of Ammon; for the border of the children of Ammon was strong.

²⁵  Israel took all these cities: and Israel lived in all the cities of the Amorites, in Heshbon, and in all the towns of it.
