Psalms 99:4 - Joseph Benson’s Commentary on the Old and New Testaments

The king's strength also loveth judgment “Although the strength of our king be infinite, yet is it never exerted but in righteousness and just judgment, which are his delight. They compose the firm basis of his throne, and direct his whole administration.” “Whoever peruses this Psalm,” says Dr. Dodd, “will find that David here, as everywhere else, considers God as the king of Israel, and himself only as his deputy. To this purpose are these expressions in the beginning of it, The Lord reigneth: The Lord is great in Zion. It is true David delighted to exert all the power that God had given him to its true purposes. He loved judgment and righteousness: but it was, in reality, God who executed them all.” Thou dost establish equity God gave them the excellent laws by which they were governed, and acted toward them with equity in all his proceedings. Thou executest judgment in Jacob Among thy own people, whom, when they act amiss, thou punishest no less than thou dost other people, (see Psalms 99:8,) whereby thou showest that thou art no respecter of persons, but a righteous and impartial judge to all sorts of men. He intends also that God, not only by his immediate providences often executed and enforced his own laws, but that he took care for the administration of justice among them by civil magistrates, who reigned by him, and by him did decree justice. These judges judged for God, and their judgment was his, 2 Chronicles 19:6.
