II. It is here promised that the Jews shall by their captivity be cured of their inclination to idolatry; this shall be the happy fruit of that affliction, even the taking away of their sin (v. 23): Neither shall they defile themselves any more with their idols, those detestable defiling things, no, nor with any of their former transgressions. Note, When one sin is sincerely parted with all sin is abandoned too, for he that hates sin, as sin, will hate all sin. And those that are cured of their spiritual idolatry, their inordinate affection to the world and the flesh, that no longer make a god of their money or their belly, have a happy blow given to the root of all their transgressions. Two ways God will take to cure them of their idolatry:—1. By bringing them out of the way of temptation to it: "I will save them out of all their dwelling-places wherein they have sinned, because there they met with the occasion of sin and allurements to it." Note, It is our wisdom to avoid the places where we have been overcome by temptations to sin, not to remain in them, or return to them, but to save ourselves out of them, as we would out of infected places; see Zech. ii. 7; Rev. xviii. 4. And it is a great mercy when God, in his providence, saves us out of the dwelling-places where we have sinned, and keeps us from harm by keeping us out of harm's way, in answer to our prayer, Lead us not into temptation, but deliver us from evil. 2. By changing the disposition of their mind: "I will cleanse them (v. 28); that is, I will sanctify them, will work in them an aversion to the pollutions of sin and a complacency in the pleasures of holiness, and then you may be sure they will not defile themselves any more with their idols." Those whom God has cleansed he will keep clean.
