Ephesians 4:27-29

And do not give the devil an opportunity [to lead you into sin by holding a grudge, or nurturing anger, or harboring resentment, or cultivating bitterness]. The thief [who has become a believer] must no longer steal, but instead he must work hard [making an honest living], producing that which is good with his own hands, so that he will have something to share with those in need. Do not let unwholesome [foul, profane, worthless, vulgar] words ever come out of your mouth, but only such speech as is good for building up others, according to the need and the occasion, so that it will be a blessing to those who hear [you speak].
