The second section is in verses 20-23, and describes the consequence of Israel's relapse in reference to the surviving Canaanite and other tribes in the land itself. Note that 'nation' in verse 20 is the term usually applied, not to Israel, but to the Gentile peoples; and that its use here seems equivalent to cancelling the choice of Israel as God's special possession, and reducing them to the level of the other nations in Canaan, to whom the same term is applied in verse 21. The stern words which are here put into the mouth of God may possibly refer to the actual message recorded in the first verses of the chapter; but, more probably, 'the Lord said' does not here mean any divine communication, but only the divine resolve, conceived as spoken to himself. It embodies the divine _lex talionis_. The punishment is analogous to the crime. Israel had broken the covenant; God would not keep His promise. That involves a great principle as to all God's promises,--that they are all conditional, and voidable by men's failure to fulfil their conditions. Observe, too, that the punishment is the retention of the occasions of the sin. Is not that, too, a law of the divine procedure to-day? Whips to scourge us are made of our pleasant vices. Sin is the punishment of sin. If we yield to some temptation, part of the avenging retribution is that the temptation abides by us, and has power over us. The 'Canaanites' whom we have allowed to lead us astray will stay beside us when their power to seduce us is done, and will pull off their masks and show themselves for what they are, our spoilers and foes. The rate of Israel's conquest was determined by Israel's faithful adherence to God. That is a standing law. Victory for us in all the good fight of life depends on our cleaving to Him, and forsaking all other. The divine motive, if we may so say, in leaving the unsubdued nations in the land, was to provide the means of proving Israel. Would it not have been better, since Israel was so weak, to secure for it an untempted period? Surely, it is a strange way of helping a man who has stumbled, to make provision that future occasions of stumbling shall lie in his path. But so the perfect wisdom which is perfect love ever ordains. There shall be no unnatural greenhouse shelter provided for weak plants. The liability to fall imposes the necessity of trial, but the trial does not impose the necessity of falling! The Devil tempts, because he hopes that we shall fall. God tries, in order that we may stand, and that our feet may be strengthened by the trial. 'I cannot praise a fugitive and cloistered virtue, unexercised and unbreathed, that never sallies out and sees her adversary, but slinks out of the race, where that immortal garland is to be run for,--not without dust and heat.'
