Matthew Poole and continuators on Proverbs 10:19

19. In the multitude of words there wanteth not sin : but he that refraineth his lips is wise.

Men that love and commonly use much talking, do frequently run into many miscarriages, because such persons, for the most part, want Wisdom to order their words aright, Eccles. 5. 3. and speak hastily without care and consideration.

That forbeareth to utter what cometh into his mind, before he hath weighed whether it be true, and fit to be spoken, or not.
