11:23 The whole land - That is, the greatest and best part of it, for some parts are expressly excepted in the following history. All that the Lord said unto Moses - God had promised to drive out the nations before them. And now the promise was fulfilled. Our successes and enjoyments are then doubly comfortable, when we see them flowing to us from the promise. This is according to what the Lord hath said: our obedience is acceptable, when it has an eye to the precept. And if we make a conscience of our duty, we need not question the performance of the promise.
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.
