1. His repentance and reformation: Ephraim shall say, What have I to do any more with idols? As some read it, God here reasons and argues with him, why he should renounce idolatry: "O Ephraim! what to me and idols? What concord or agreement can there be between me and idols? What communion between light and darkness, between Christ and Belial? 2 Cor. vi. 14, 15. Therefore thou must break off thy league with them if thou wilt come into covenant with me." As we read it, God promises to bring Ephraim and keep him to this: Ephraim shall say, God will put it into his heart to say it, What have I to do any more with idols? He has promised (v. 3) not to say any more to the works of his hands, You are my gods. But God's promises to us are much more our security and our strength for the mortifying of sin than our promises to God; and therefore God himself is here surety for his servant to good, will put in into his heart and into his mouth. And, whatever good we say or do at any time, it is he that works it in us. Ephraim had solemnly engaged not to call his idols his gods; but God here engages further for him that he shall resolve to have no more to do with them. He shall abolish them, he shall abandon them, and that with the utmost detestation; for it is necessary not only that in our lives we be turned from sin, but that in our hearts we be turned against sin. See here, (1.) The power of divine grace. Ephraim had been joined to his idols (ch. iv. 17), was so fond of them that one would have thought he could never fall out with them; and yet God will work such a change in him that he shall loathe them as much as ever he loved them. (2.) See the benefit of sanctified afflictions. Ephraim had smarted for his idolatry; it had brought one judgment after another upon him, and this at length is the fruit, even the taking away of his sin, Isa. xxvii. 9. (3.) See the nature of repentance; it is a firm and fixed resolution to have no more to do with sin. This is the language of the penitent: "I am ashamed that ever I had to do with sin; but I have had enough of it; I hate it, and by the grace of God I will never have any thing to do with it again, no, not with the occasions of it." Thou shalt say to thy idol, Get thee hence (Isa. xxx. 22), shalt say to the tempter, Get thee behind me, Satan.
