Proverbs 4:24

Put away from thee a froward mouth
A mouth speaking froward and perverse things; things contrary to right reason, to the law of God, and Gospel of Christ; blasphemies against God or men; every thing that is untrue, unchaste, unjust, foolish, and filthy; all swearing, lying, and everything that is repugnant to truth and justice. Some understand it of men that are liars, blasphemers, and froward persons, who are to be shunned and avoided, and to be debarred the houses and society of good men; and perverse lips put far from thee;
do not make use of them thyself, nor keep company with men of such a character. Much the same thing is meant as before.
