Open thy mouth, judge righteously,.... Having heard the cause, pronounce a righteous sentence; deliver it freely and impartially, with all readiness and boldness, not caring for the censures of wicked and unjust men;

and plead the cause of the poor and needy; who are oppressed by the rich, cannot plead for themselves, nor fee others to plead for them; do thou do it freely and faithfully. Thus as Lemuel's mother cautions him against women and wine, she advises him to do the duties of his office in administering impartial justice to all, and particularly in being the advocate and judge of the indigent and distressed.

Open thy mouth, judge righteously, and plead the cause of the poor and needy.

31:1-9 When children are under the mother's eye, she has an opportunity of fashioning their minds aright. Those who are grown up, should often call to mind the good teaching they received when children. The many awful instances of promising characters who have been ruined by vile women, and love of wine, should warn every one to avoid these evils. Wine is to be used for want or medicine. Every creature of God is good, and wine, though abused, has its use. By the same rule, due praise and consolation should be used as cordials to the dejected and tempted, not administered to the confident and self-sufficient. All in authority should be more carefully temperate even than other men; and should be protectors of those who are unable or afraid to plead their own cause. Our blessed Lord did not decline the bitterest dregs of the cup of sorrow put into his hands; but he puts the cup of consolation into the hands of his people, and causes those to rejoice who are in the deepest distress.
