Joshua 11:6

Hough their horses, i.e. cut their hamstrings, that they may be unfit for war. For God forbade them to have or keep many horses, Deuteronomy 17:16, now especially, that they might not trust to their horses, as men are apt to do, nor distrust God for want of so necessary a help in battle; nor ascribe the conquest of the land to their own strength, but wholly to God, by whose power alone a company of raw and unexperienced footmen were able to subdue so potent a people, which besides their great numbers, and giants, and walled cities, had the advantage of many thousands of horses and chariots.
