I. He is a God of inflexible justice, a jealous God, and will take vengeance on his enemies; let Nineveh know this, and tremble before him. Their idols are insignificant things; there is nothing formidable in them. But the God of Israel is greatly to be feared; for, 1. He resents the affronts and indignities done him by those that deny his being or any of his perfections, that set up other gods in competition with him, that destroy his laws, arraign his proceedings, ridicule his word, or are abusive to his people. Let such know that Jehovah, the one only living and true God, is a jealous God, and a revenger; he is jealous for the comfort of his worshippers, jealous for his land (Joel ii. 18), and will not have that injured. He is a revenger, and he is furious; he has fury (so the word is), not as man has it, in whom it is an ungoverned passion (so he has said, Fury is not in me, Isa. xxvii. 4), but he has it in such a way as becomes the righteous God, to put an edge upon his justice, and to make it appear more terrible to those who otherwise would stand in no awe of it. He is Lord of anger (so the Hebrew phrase is for that which we read, he is furious); he has anger, but he has it at command and under government. Our anger is often lord over us, as theirs that have no rule over their own spirits, but God is always Lord of his anger and weighs a path to it, Ps. lxxviii. 50. 2. He resolves to reckon with those that put those affronts upon him. We are told here, not only that he is a revenger, but that he will take vengeance; he has said he will, he has sworn it, Deut. xxxii. 40, 41. Whoever are his adversaries and enemies among men, he will make them feel his resentments; and, though the sentence against his enemies is not executed speedily, yet he reserves wrath for them and reserves them for it in the day of wrath. Against his own people, who repent and humble themselves before him, he keeps not his anger for ever, but against his enemies he will for ever let out his anger. He will not at all acquit the wicked that sin, and stand to it, and do not repent, v. 3. Those wickedly depart from their God that depart, and never return (Ps. xviii. 21), and these he will not acquit. Humble supplicants will find him gracious, but scornful beggars will not find him easy, or that the door of mercy will be opened to a loud, but late, Lord, Lord. This revelation of the wrath of God against his enemies is applied to Nineveh (v. 8), and should be applied by all those to themselves who go on still in their trespasses: With an over-running flood he will make an utter end of the place thereof. The army of the Chaldeans shall overrun the country of the Assyrians, and lay it all waste. God's judgments, when they come with commission, are like a deluge to any people, which they cannot keep off nor make head against. Darkness shall pursue his enemies; terror and trouble shall follow them, whithersoever they go, shall pursue them to utter darkness; if they think to flee from the darkness which pursues them they will but fall into that which is before them.
