Mercy and truth preserve the king: and his throne is upholden by mercy.

Jamieson-Fausset-Brown Bible Commentary

28. (Compare Pr 3:3; 16:6, 12).

Matthew Henry's Concise Commentary

20:23. A bargain made by fraud will prove a losing bargain in the end. 24. How can we form plans, and conduct business, independently of the Lord? 25. The evasions men often use with their own consciences show how false and deceitful man is. 26. Justice should crush the wicked, and separate them from the virtuous. 27. The rational soul and conscience are as a lamp within us, which should be used in examining our dispositions and motives with the revealed will of God. 28. Mercy and truth are the glories of God's throne. 29. Both young and old have their advantages; and let neither despise or envy the other.

Matthew Henry's Whole Bible Commentary

Verse 28

Here we have, 1. The virtues of a good king. Those are mercy and truth, especially mercy, for that is mentioned twice here. He must be strictly faithful to his word, must be sincere, and abhor all dissimulation, must religiously discharge all the trusts reposed in him, must support and countenance truth. He must likewise rule with clemency, and by all acts of compassion gain the affections of his people. Mercy and truth are the glories of God's throne, and kings are called gods. 2. The advantages he gains thereby. These virtues will preserve his person and support his government, will make him easy and safe, beloved by his own people and feared by his enemies, if it be possible that he should have any.
