III. They shall be cured of their idolatry, shall fall out with their idols, and never be reconciled to them again, v. 22. The deliverance God shall work for them shall convince them that it is their interest, as well as duty, to serve him only; and they shall own that, as their trouble was brought upon them for their idolatries, so it was removed upon condition that they should not return to them. This is also the good effect of their seeing their teachers and hearing the word behind them; by this it shall appear that they are the better for the means of grace they enjoy—they shall break off from their best-beloved sin. Observe, 1. How foolishly mad they had formerly been upon their idols, in the day of their apostasy. Idolaters are said to be mad upon their idols (Jer. l. 38), doatingly fond of them. They had graven images of silver, and molten images of gold, and, though gold needs no painting, they had coverings and ornaments on these; they spared no cost in doing honour to their idols. 2. How wisely mad (if I may so speak) they now were at their idols, what a holy indignation they conceived against them in the day of their repentance. They not only degraded their images, but defaced them, not only defaced them, but defiled them; they not only spoiled the shape of them, but in a pious fury threw away the gold and silver they were made of, though otherwise valuable and convertible to a good use. They could not find in their hearts to make any vessel of honour of them. The rich clothes wherewith their images were dressed up they cast away as a filthy cloth which rendered those that touched it unclean until the evening, Lev. xv. 23. Note, To all true penitents sin has become very odious; they loathe it, and loathe themselves because of it; they cast it away to the dunghill, the fittest place for it, nay, to the cross, for they crucify the flesh; their cry against it is, Crucify it, crucify it. They say unto it, Abi hinc in malam rem—Get thee hence. They are resolved never to harbour it any more. They put as far from as they can all the occasions of sin and temptations to it, though they are as a right eye or a right hand, and protest against it as Ephraim did (Hos. xiv. 8), What have I to do any more with idols? Probably this was fulfilled in many particular persons, who, by the deliverance of Jerusalem from Sennacherib's army, were convinced of the folly of their idolatry and forsook it. It was fulfilled in the body of the Jewish nation at their return from their captivity in Babylon, for they abhorred idols ever after; and it is accomplished daily in the conversion of souls, by the power of divine grace, from spiritual idolatry to the fear and love of God. Those that join themselves to the Lord must abandon every sin, and say unto it, Get thee hence.
