11:10-14 The Canaanites filled up the measure of their iniquity, and were, as a judgment, left to the pride, obstinacy, and enmity of their hearts, and to the power of Satan; all restraints being withdrawn, while the dispensations of Providence tended to drive them to despair. They brought on themselves the vengeance they justly merited, of which the Israelites were to be executioners, by the command the Lord gave to Moses.
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.
