11 Be very careful, therefore, to love the Lord your God. 12 For if you turn back, and join the survivors of these nations left here among you, and intermarry with them, so that you marry their women and they yours, 13 know assuredly that the Lord your God will not continue to drive out these nations before you; but they shall be a snare and a trap for you, a scourge on your sides, and thorns in your eyes, until you perish from this good land that the Lord your God has given you. 14 "And now I am about to go the way of all the earth, and you know in your hearts and souls, all of you, that not one thing has failed of all the good things that the Lord your God promised concerning you; all have come to pass for you, not one of them has failed 15 But just as all the good things that the Lord your God promised concerning you have been fulfilled for you, so the Lord will bring upon you all the bad things, until he has destroyed you from this good land that the Lord your God has given you. 16 If you transgress the covenant of the Lord your God, which he enjoined on you, and go and serve other gods and bow down to them, then the anger of the Lord will be kindled against you, and you shall perish quickly from the good land that he has given to you."
Matthew Henry's Commentary on Joshua 23:11-16
Commentary on Joshua 23:11-16
(Read Joshua 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, Hebrews 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.
