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 thou shalt not escape sin; But if thou refrain thy lips thou wilt 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 want.
