(2.) He had marked them for ruin, v. 7, 9, 11. Those that will not know God as their lawgiver shall be made to know him as their judge. God determines here to bring his judgments upon them, for the refining of some and the ruining of the rest. [1.] Some shall be refined (v. 7): "Because they are thus corrupt, behold I will melt them and try them, will bring them into trouble and see what that will do towards bringing them to repentance, whether the furnace of affliction will purify them from their dross, and whether, when they are melted, they will be new-cast in a better mould." He will make trial of less afflictions before he brings upon them utter destruction; for he desires not the death of sinners. They shall not be rejected as reprobate silver till the founder has melted in vain, ch. vi. 29, 30. For how shall I do for the daughter of my people? He speaks as one consulting with himself what to do with them that might be for the best, and as one that could not find in his heart to cast them off and give them up to ruin till he had first tried all means likely to bring them to repentance. Or, "How else shall I do for them? They have grown so very corrupt that there is no other way with them but to put them into the furnace; what other course can I take with them? Isa. v. 4, 5. It is the daughter of my people, and I must do something to vindicate my own honour, which will be reflected upon if I connive at their wickedness. I must do something to reduce and reform them." A parent corrects his own children because they are his own. Note, When God afflicts his people, it is with a gracious design to mollify and reform them; it is but when need is and when he knows it is the best method he can use. [2.] The rest shall be ruined (v. 9): Shall I not visit for these things? Fraud and falsehood are sins which God hates and which he will reckon for. "Shall not my soul be avenged on such a nation as this, that is so universally corrupt, and, by its impudence in sin, even dares and defies divine vengeance? The sentence is passed, the decree has gone forth (v. 11): I will make Jerusalem heaps of rubbish, and lay it in such ruins that it shall be fit for nothing but to be a den of dragons; and the cities of Judah shall be a desolation." God makes them so, for he gives the enemy warrant and power to do it: but why is the holy city made a heap? The answer is ready, Because it has become an unholy one?
