Young's Literal Translation

²⁴ And Israel smiteth him by the mouth of the sword, and possesseth his land from Arnon unto Jabbok -- unto the sons of Ammon; for the border of the sons of Ammon [is] strong.

²⁵ And Israel taketh all these cities, and Israel dwelleth in all the cities of the Amorite, in Heshbon, and in all its villages;

²⁶ for Heshbon is a city of Sihon king of the Amorite, and he hath fought against the former king of Moab, and taketh all his land out of his hand, unto Arnon;
