Matthew Henry and continuators on Proverbs 21:15

15 It is joy to the just to do judgment: but destruction shall be to the workers of iniquity.

Note, 1. It is a pleasure and satisfaction to good men both to see justice administered by the government they live under, right taking place and iniquity suppressed, and also to practise it themselves, according as their sphere is. They not only do justice, but do it with pleasure, not only for fear of shame, but for love of virtue. 2. It is a terror to wicked men to see the laws put in execution against vice and profaneness. It is destruction to them; as it is also a vexation to them to be forced, either for the support of their credit or for fear of punishment, to do judgment themselves. Or, if we take it as we read it, the meaning is, There is true pleasure in the practice of religion, but certain destruction at the end of all vicious courses.
