Prov 16:12

“Here is, 1. The character of a good king, which Solomon intended not for his own praise, but for instruction to his successors, his neighbours, and the viceroys under him. A good king not only does justice, but it is an abomination to him to do otherwise. He hates the thought of doing wrong and perverting justice; he not only abhors the wickedness done by others, but abhors the wickedness done by others, but abhors to do any himself, though, having power, he might easily and safety do it. 2. The comfort of a good king: His throne is established by righteousness. He that makes conscience of using his power aright shall find that to be the best security of his government, both as it will oblige people, make them easy, and keep them in the interest of it, and as it will obtain the blessing of God, which will be a firm basis to the throne and a strong guard about it.”

“It is an abomination to kings to commit wickedness,.... The Targum is, "the abomination of kings are they that work wickedness.'' It should be an abomination to kings to commit wickedness themselves, and those that do it should be abhorred by them, or they should show their resentment at it by removing them from their presence, or by punishing them: and though there have been such kings as David, Psa 101:4; yet there are but few such; this is not true of kings in common; and therefore rather expresses what they should be than what they are; but is perfectly applicable to Christ, who loves righteousness and hates iniquity, Psa 45:7; for the throne is established by righteousness; this is the support, strength, and security of every kingdom, and of the thrones of kings; and it is with judgment and righteousness that the throne of Christ is established; yea, justice and judgment are the habitation of his throne, Isa 9:7.”

“12 It is an abomination to kings to commit wickedness, For by righteousness the throne is established. As 10b uttered a warning to the king, grounded on the fact of 10a, so 12a indirectly contains a warning, which is confirmed by the fact 12b. It is a fact that the throne is established by righteousness (יכּון as expressive of a rule, like הוּכן, Isa 16:5, as expressive of an event); on this account it is an abomination to kings immediately or mediately to commit wickedness, i.e., to place themselves in despotic self-will above the law. Such wicked conduct shall be, and ought to be, an abhorrence to them, because they know that they thereby endanger the stability of their throne. This is generally the case, but especially was it so in Israel, where the royal power was never absolutistic; where the king as well as the people were placed under God's law; where the existence of the community was based on the understood equality of right; and the word of the people, as well as the word of the prophets, was free. Another condition of the stability of the throne is, after Pro 25:5, the removal of godless men from nearness to the king. Rehoboam lost the greater part of his kingdom by this, that he listened to the counsel of the young men who were hated by the people.”
