3. Punishments shall be public and open: I will execute these judgments in the sight of the nations (v. 8); the judgments themselves shall be so remarkable that all the nations far and near shall take notice of them; they shall be all the talk of that part of the world, and the more for the conspicuousness of the place and people on which they are inflicted. Note, Public sins, as they call for public reproofs (those that sin rebuke before all), so, if those prevail not, they call for public judgments. He strikes them as wicked men in the open sight of others (Job xxxiv. 26), that he may maintain and vindicate the honour of his government, for (as Grotius descants upon it here) why should he suffer it to be said, See what wicked lives those lead who profess to be the worshippers of the only true God! And, as the publicity of the judgments will redound to the honour of God, so it will serve, (1.) To aggravate the punishment, and to make it lie the more heavily. Jerusalem, being made waste, becomes a reproach among the nations in the sight of all that pass by, v. 14. The more conspicuous and the more peculiar any have been in the day of their prosperity the greater disgrace attends their fall; and that was Jerusalem's case. The more Jerusalem had been a praise in the earth the more it is now a reproach and a taunt, v. 15. This she was warned of as much as any thing when her glory commenced (1 Kings ix. 8), and this was lamented as much as any thing when it was laid in the dust, Lam. ii. 15. (2.) To teach the nations to fear before the God of Israel, when they see what a jealous God he is, and how severely he punishes sin even in those that are nearest to him: It shall be an instruction to the nations, v. 15. Jerusalem should have taught her neighbours the fear of God by her piety and virtue, but, she not doing that, God will teach it to them by her ruin; for they have reason to say, If this be done in the green tree, what shall be done in the dry? If judgment begin at the house of God, where will it end? If those be thus punished who only had some idolaters among them, what will become of us who are all idolaters? Note, The destruction of some is designed for the instruction of others. Malefactors are publicly punished in terrorem—that others may take warning.
