Else if ye do - go back - The soldier who draws back when going to meet the enemy, forfeits his life. These were the Lord's soldiers, and if they drew back they drew back unto perdition, their lives being forfeited by their infidelity.

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,

Else if ye do in any wise go back, and cleave unto the remnant of these nations, even these that remain among you, and shall make marriages with them, and go in unto them, and they to you:

23:12 Go back - From God, and from his worship and service.

Jos 23:12. By Threatenings in Case of Disobedience.

12, 13. Else if ye do in any wise go back, and cleave unto the remnant of these nations-As marriage connections with the idolatrous Canaanites would present many and strong temptations to transgress it, these were strictly prohibited (Ex 34:12-16; De 7:3). With his eye, as it were, upon those prohibitions, Joshua threatens them with the certain withdrawal of the divine aid in the further expulsion of the Canaanites (a threat founded Ex 23:33; Nu 33:55; De 7:16).

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.
