11:18 A long time - For divers years together, as is evident by the following history. And this is here expressed, lest it should be thought that as all these wars are here recorded in a short narration, so they were dispatched in a short time. And God would have the land to be conquered gradually, for many weighty reasons; Lest the sudden extirpation of those nations should have made a great part of the land desert, and thereby have increased the number of wild beasts, Deut 7:22. Lest being done suddenly and easily, it should soon be forgotten and despised, as the nature of man is apt to do in those cases. That by long exercise the Israelites might grow skilful in the art of war. For the trial and exercise of their patience and courage, and trust in God. To oblige them to the greater care to please God, whom they yet need for their help against their enemies.
11:15-23 Never let the sons of Anak be a terror to the Israel of God, for their day to fall will come. The land rested from war. It ended not in a peace with the Canaanites, that was forbidden, but in a peace from them. There is a rest, a rest from war, remaining for the people of God, into which they shall enter, when their warfare is accomplished. That which was now done, is compared with what had been said to Moses. God's word and his works, if viewed together, will be found mutually to set each other forth. If we make conscience of our duty, we need not question the performance of the promise. But the believer must never put off his armour, or expect lasting peace, till he closes his eyes in death; nay, as his strength and usefulness increase, he may expect more heavy trials; yet the Lord will not permit any enemies to assault the believer till he has prepared him for the battle. Christ Jesus ever lives to plead for his people, and their faith shall not fail, however Satan may be permitted to assault them. And however tedious, sharp, and difficult the believer's warfare, his patience in tribulation may be encouraged by the joyfulness of hope; for he will, ere long, rest from sin and from sorrow in the Canaan above.
