9. Joshua did unto them as the Lord bade him--(See Jos 11:6). Houghing the horses is done by cutting the sinews and arteries of their hinder legs, so that they not only become hopelessly lame, but bleed to death. The reasons for this special command were that the Lord designed to lead the Israelites to trust in Him, not in military resources (Ps 20:7); to show that in the land of promise there was no use of horses; and, finally, to discourage their travelling as they were to be an agricultural, not a trading, people.
