(12,13) if ye . . . make marriages with them . . . the Lord your God will no more drive out.--The common-sense of this warning is manifest. The God of Israel cannot treat as His enemies those whom Israel has united with itself, unless He also makes war on Israel. It was a long time before Israel learned the lesson how to live in the world without being of the world. It was not learnt until after the Babylonish captivity, and when learnt, it soon developed into a Pharisaical exclusiveness, which produced the very opposite effect to that which the law was intended to have.

Verse 12. - Go back. Literally, return. Cleave. A word (see ver. 8) signifying close and intimate relationship. And the intimacy of the relationship is indicated, as in ver. 8, by the use of the preposition בְּ. Make marriages with them. No closer or more intimate relationship is possible than this. Nothing, therefore, would be more certain to draw the Israelites away from their allegiance to God, and to seduce them and their children into the false and corrupt worship of the nations around them. "Unde deprecor vos qui fidelis estis, ut ita vitam vestram et conversationem servetis, ne in aliquo vel ipsi scandalum patiamini vel aliis scandalum faciatis; sit in vobis summi studii, summaeque cautelae, ne quis in hanc sanctam congregationem vestram pollutus introeat" (Orig., Hom. 21 on Joshua). Go in unto them. Rather, go among them. Spoken of the familiar intercourse of friendship. It is equivalent to our words "associate with them."

23:11-16 Would we cleave to the Lord, we must always stand upon our guard, for many a soul is lost through carelessness. Love the Lord your God, and you will not leave him. Has God been thus true to you? Be not you false to him. He is faithful that has promised, Heb 10:23. The experience of every Christian witnesses the same truth. Conflicts may have been severe and long, trials great and many; but at the last he will acknowledge that goodness and mercy followed him all the days of his life. Joshua states the fatal consequences of going back; know for a certainty it will be your ruin. The first step would be, friendship with idolaters; the next would be, marrying with them; the end of that would be, serving their gods. Thus the way of sin is down-hill, and those who have fellowship with sinners, cannot avoid having fellowship with sin. He describes the destruction he warns them of. The goodness of the heavenly Canaan, and the free and sure grant God has made of it, will add to the misery of those who shall for ever be shut out from it. Nothing will make them see how wretched they are, so much, as to see how happy they might have been. Let us watch and pray against temptation. Let us trust in God's faithfulness, love, and power; let us plead his promises, and cleave to his commandments, then we shall be happy in life, in death, and for ever.Else if ye do in any wise go back,.... From the Lord and his worship, from his word and ordinances:

and cleave unto the remnant of these nations, even those that remain among you; in cities not taken, or in several which the Philistines were in possession of, or lived among them as tributaries to them, if they should take to them, and be free and familiar with them, which may lead on to nearer connections in civil and religious matters:

and shall make marriages with them; marry their daughters to the sons of Canaanites, or admit the daughters of Canaanites to be married to their sons:

and go in unto them, and they to you; which is expressive of the consummation of marriage, and of the performance of the conjugal duty,
