2. How he describes the destruction which he warns them of. He tells them, (1.) That these remainders of the Canaanites, if they should harbour them, and indulge them, and join in affinity with them, would be snares and traps to them, both to draw them to sin (not only to idolatry, but to all immoralities, which would be the ruin, not only of their virtue, but of their wisdom and sense, their spirit and honour), and also to draw them into foolish bargains, unprofitable projects, and all manner of inconveniences; and having thus by underhand practices decoyed them into one mischief or other, so as to gain advantages against them, they would then act more openly, and be scourges in their sides and thorns in their eyes, would perhaps kill or drive away their cattle, burn or steal their corn, alarm or plunder their houses, and would be all ways possible be vexatious to them; for, whatever pretences of friendship they might make, a Canaanite, unless proselyted to the faith and worship of the true God, would in every age hate the very name and sight of an Israelite. See how the punishment would be made to answer the sin, nay, how the sin itself would be the punishment. (2.) That the anger of the Lord would be kindled against them. Their making leagues with the Canaanites would not only give those idolaters the opportunity of doing them a mischief, and be the fostering of snakes in their bosoms, but it would likewise provoke God to become their enemy, and would kindle the fire of his displeasure against them. (3.) That all the threatenings of the word would be fulfilled, as the promise had been, for the God of eternal truth is faithful to both (v. 15): "As all good things have come upon you according to the promise, so long as you have kept close to God, so all evil things will come upon you according to the threatening, if you forsake him." Moses had set before them good and evil; they had experienced the good, and were now in the enjoyment of it, and the evil would as certainly come if they were disobedient. As God's promises are not a fool's paradise, so his threatenings are not bugbears. (4.) That it would end in the utter ruin of their church and nation, as Moses had foretold. This is three times mentioned here. Your enemies will vex you until you perish from off this good land, v. 13. Again, "God will plague you until he have destroyed you from off this good land, v. 15. Heaven and earth will concur to root you out, so that (v. 16) you shall perish from off the good land." It will aggravate their perdition that the land from which they shall perish is a good land, and a land which God himself had given them, and which therefore he would have secured to them if they by their wickedness had not thrown themselves out of it. Thus the goodness of the heavenly Canaan, and the free and sure grant God has made of it, will aggravate the misery of those that shall for ever be shut out and perish from it. Nothing will make them see how wretched they are so much as to see how happy they might have been. Joshua thus sets before them the fatal consequences of their apostasy, that, knowing the terror of the Lord, they might be persuaded with purpose of heart to cleave to him.
