Take {g} away the wicked from before the king, and his throne shall be established in righteousness.

(g) It is not enough that he is pure himself, but that he put away others who are corrupted.

Jamieson-Fausset-Brown Bible Commentary

5. before-or, "in presence of," as courtiers stood about a king.

Matthew Henry's Concise Commentary

25:1-3 God needs not search into any thing; nothing can be hid from him. But it is the honour of rulers to search out matters, to bring to light hidden works of darkness. 4,5. For a prince to suppress vice, and reform his people, is the best way to support his government. 6,7. Religion teaches us humility and self-denial. He who has seen the glory of the Lord in Christ Jesus, will feel his own unworthiness. 8-10. To be hasty in beginning strife, will bring into difficulties. War must at length end, and might better be prevented. It is so in private quarrels; do all thou canst to settle the matter. 11,12. A word of counsel, or reproof, rightly spoken, is especially beautiful, as fine fruit becomes still more beautiful in silver baskets. 13. See what ought to be the aim of him that is trusted with any business; to be faithful. A faithful minister, Christ's messenger, should be thus acceptable to us. 14. He who pretends to have received or given that which he never had, is like the morning cloud, that disappoints those who look for rain. 15. Be patient to bear a present hurt. Be mild to speak without passion; for persuasive language is the most effectual to prevail over the hardened mind. 16. God has given us leave to use grateful things, but we are cautioned against excess.

Matthew Henry's Whole Bible Commentary

Verses 4-5

This shows that the vigorous endeavour of a prince to suppress vice, and reform the manners of his people, is the most effectual way to support his government. Observe, 1. what the duty of magistrates is: To take away the wicked, to use their power for the terror of evil works and evil workers, not only to banish those that are vicious and profane from their presence, and forbid them the court, but so to frighten them and restrain them that they may not spread the infection of their wickedness among their subjects. This is called taking away the dross from the silver, which is done by the force of fire. Wicked people are the dross of a nation, the scum of the country, and, as such, to be taken away. If men will not take them away, God will, Ps. 119:119. If the wicked be taken away from before the king, if he abandon them and show his detestation of their wicked courses, it will go far towards the disabling of them to do mischief. The reformation of the court will promote the reformation of the kingdom, Ps. 101:3, 8. 2. What the advantage will be of their doing this duty. (1.) It will be the bettering of the subjects; they shall be made like silver refined, fit to be made vessels of honour. (2.) It will be the settling of the prince. His throne shall be established in this righteousness, for God will bless his government, the people will be pliable to it, and so it will become durable.
