17Instruction keeps the right ways of life; but instruction unchastened goes astray.
18Righteous lips cover enmity; but they that utter railings are most foolish.
19By a multitude of words you shall not escape sin; but if you refrain your lips you will be prudent.
20The tongue of the just is tried silver; but the heart of the ungodly shall fail.
21The lips of the righteous know sublime truths: but the foolish die in lack.
