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

²⁵And Israel took all these cities: and Israel dwelt in all the cities of the Amorites, in Heshbon, and in all the towns thereof.
