Matthew Henry, on Prov 20:26

“A wise king scattereth the wicked, and bringeth over them the wheel.”

“See here, 1. What is the business of magistrates. They are to be a terror to evil-doers. They must scatter the wicked, who are linked in confederacies to assist and embolden one another in doing mischief; and there is no doing this but by bringing the wheel over them, that is, putting the laws in execution against them, crushing their power and quashing their projects. Severity must sometimes be used to rid the country of those that are openly vicious and mischievous, debauched and debauching. 2. What is the qualification of magistrates, which is necessary in order to do this. They have need to be both pious and prudent, for it is the wise king, who is both religious and discreet, that is likely to effect the suppression of vice and reformation of manners.”
