John Gill's Exposition of the Whole Bible
Proverbs 28:16
The prince that wanteth understanding [is] also a great oppressor,.... Or, "much in oppressions" o; he multiplies them, and abounds in them; he distresses his subjects in a variety of ways and methods he uses to extort money from them by which he shows his want of understanding: he is a wise prince that uses gentle methods, and gains the affections of his people, and who cheerfully supports his crown and government with honour and glory; but he is a foolish prince that uses them with rigour. It may be rendered, "and a prince that wanteth understanding, and is much", or "abounds, in oppressions"; in laying heavy burdens and taxes on his people, in an arbitrary manner; "shall shorten, and not prolong his days" p, as it may be supplied from the next clause; either his subjects will rise up against him, and dethrone him, and destroy him; or God, in mercy to them, and in judgment to him, will remove him by death;
[but] he that hateth covetousness shall prolong [his] days; to hate covetousness is a good qualification of a civil magistrate, prince, or ruler, Exodus 18:21. This sin is the cause of a wicked prince oppressing his subjects; but where it is hated, which is seen by moderation in government, and easing of the people as much as possible; such a prince, as he has the hearts of his subjects, is well pleasing to God, by whom he reigns; and such an one, through the prayers of the people for him, and the goodness of God unto him, lives long, and reigns prosperously; and dies, as David, in a good old age, full of days, riches, and honour.
