I. God will certainly execute judgment upon them for their idolatries. Let them expect it, for the decree has gone forth. 1. God sees all their sins, though they commit them ever so secretly and palliate them ever so artfully (v. 17): My eyes are upon all their ways. They have not their eye upon God, have no regard to him, stand in no awe of him; but he has his eye upon them; neither they nor their sins are hidden from his face, from his eyes. Note, None of the sins of sinners either can be concealed from God or shall be overlooked by him, Prov. v. 21; Job xxxiv. 21; Ps. xc. 8. 2. God is highly displeased, particularly at their idolatries, v. 18. As his omniscience convicts them, so his justice condemns them: I will recompense their iniquity and their sin double, not double to what it deserves, but double to what they expect and to what I have done formerly. Or I will recompense it abundantly; they shall now pay for their long reprieve and the divine patience they have abused. The sin for which God has a controversy with them is their having defiled God's land with their idolatries, and not only alienated that which he was entitled to as his inheritance, but polluted that which he dwelt in with delight as his inheritance, and made it offensive to him with the carcases of their detestable things, the gods themselves which they worshipped, the images of which, though they were of gold and silver, were as loathsome to God as the putrid carcases of men or beasts are to us. Idols are carcases of detestable things. God hates them, and so should we. Or he might refer to the sacrifices which they offered to these idols, with which the land was filled; for they had high places in all the coasts and corners of it. This was the sin which, above any other, incensed God against them. 3. He will find out and raise up instruments of his wrath, that shall cast them out of their land, according to the sentence passed upon them (v. 16): I will send for many fishers and many hunters—the Chaldean army, that shall have many ways of ensnaring and destroying them, by fraud as fishers, by force as hunters. They shall find them out wherever they are, and shall chase and closely pursue them, to their ruin. They shall discover them wherever they are hid, in hills or mountains, or holes of the rocks, and shall drive them out. God has various ways of prosecuting a people with his judgments that avoid the convictions of his word. He has men at command fit for his purpose; he has them within call, and can send for them when he pleases. 4. Their bondage in Babylon shall be sorer and much more grievous than that in Egypt, their task-masters more cruel, and their lives made more bitter. This is implied in the promise (v. 14, 15), that their deliverance out of Babylon shall be more illustrious in itself, and more welcome to them, than that out of Egypt. Their slavery in Egypt came upon them gradually and almost insensibly; that in Babylon came upon them at once and with all the aggravating circumstances of terror. In Egypt they had a Goshen of their own, but none such in Babylon. In Egypt they were used as servants that were useful, in Babylon as captives that had been hateful. 5. They shall be warned, and God shall be glorified, by these judgments brought upon them. These judgments have a voice, and speak aloud, (1.) Instruction to them. When God chastens them he teaches them. By this rod God expostulates with them (v. 20): "Shall a man make gods to himself? Will any man be so perfectly void of all reason and consideration as to think that a god of his own making can stand him in any stead? Will you ever again be such fools as you have been, to make to yourselves gods which are no gods, when you have a God whom you may call your own, who made you, and is himself the true and living God?" (2.) Honour to God; for he will be known by the judgments which he executes. He will first recompense their iniquity (v. 18), and then he will this once (v. 21)—this once for all, not by many interruptions of their peace, but this one desolation and destruction of it. "For this once, and no more, I will cause them to know my hand, the length and weight of my punishing hand, how far it can reach and how deeply it can wound. And they shall know that my name is Jehovah, a God with whom there is no contending, who gives being to threatenings and puts life into them as well as promises."
