Here is, 1. The duty of magistrates, and that is, to judge faithfully between man and man, and to determine all causes brought before them, according to truth and equity, particularly to take care of the poor, not to countenance them in an unjust cause for the sake of their poverty (Exo 23:3), but to see that their poverty do not turn to their prejudice if they have a just cause. The rich will look to themselves, but the poor and needy the prince must defend (Psa 82:3) and plead for, Pro 31:9. 2. The happiness of those magistrates that do their duty. Their throne of honour, their tribunal of judgment, shall be established for ever. This will secure to them the favour of God and strengthen their interest in the affections of their people, both which will be the establishment of their power, and help to transmit it to posterity and perpetuate it in the family.

The king that faithfully judgeth the poor,.... That truly executes justice and judgment among all his subjects, particularly the poor, who are too often neglected, because they cannot afford persons to plead their cause: such a king was Solomon; and especially the Messiah, of whom he was a type, Psa 72:1;

his throne shall be established for ever; be secure to him as long as he lives, and to his posterity after; justice to all men, and mercy to the poor, are the support of a prince's throne; see Pro 20:28.

(Compare Pro 20:28; Pro 25:5). Such is the character of the King of kings (Psa 72:4, Psa 72:12).
