Proverbs 31:26 - Joseph Benson’s Commentary on the Old and New Testaments

She openeth her mouth with wisdom She is neither sullenly silent, nor full of impertinent talk, but speaks discreetly and piously, as occasion offers. In her tongue is the law of kindness Her speeches are guided by wisdom and grace, and not by inordinate passions. And this practice is called a law in her tongue, because it is constant and customary, and proceeds from an inward and powerful principle of true wisdom.
