John Wesley on Proverbs 31:26

Openeth her mouth - She is neither sullenly silent, nor full of impertinent talk, but speaks discreetly and piously, as occasion offers. In her tongue - 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.
