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.
