Matthew Henry and continuators on Proverbs 20:8

8 A king that sitteth in the throne of judgment scattereth away all evil with his eyes.

Here is, 1. The character of a good governor: He is a king that deserves to be called so who sits in the throne, not as a throne of honour, to take his ease, and take state upon him, and oblige men to keep their distance, but as a throne of judgment, that he may do justice, give redress to the injured and punish the injurious, who makes his business his delight and loves no pleasure comparably to it, who does not devolve the whole care and trouble upon others, but takes cognizance of affairs himself and sees with his own eyes as much as may be, 1 Kings x. 9. 2. The happy effect of a good government. The presence of the prince goes far towards the putting of wickedness out of countenance; if he inspect his affairs himself, those that are employed under him will be kept in awe and restrained from doing wrong. If great men be good men, and will use their power as they may and ought, what good may they do and what evil may they prevent!
