  Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers.

  If anyone among you thinks he is religious, and does not bridle his tongue but deceives his own heart, this one’s religion is useless.
   
• James 3:6-10
  And the tongue is a fire, a world of iniquity. The tongue is so set among our members that it defiles the whole body, and sets on fire the course of nature; and it is set on fire by hell. For every kind of beast and bird, of reptile and creature of the sea, is tamed and has been tamed by mankind. But no man can tame the tongue. It is an unruly evil, full of deadly poison. With it we bless our God and Father, and with it we curse men, who have been made in the similitude of God. Out of the same mouth proceed blessing and cursing. My brethren, these things ought not to be so.

  Indeed, we put bits in horses' mouths that they may obey us, and we turn their whole body. Look also at ships: although they are so large and are driven by fierce winds, they are turned by a very small rudder wherever the pilot desires. Even so the tongue is a little member and boasts great things. See how great a forest a little fire kindles!

  For in so doing you will heap coals of fire on his head."
  Do not be overcome by evil, but overcome evil with good.
