Matthew 12:36-37 : 36 But I say unto you, that every idle word that men shall speak, they shall render an account for it in the day of judgment. 37 For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
Matthew 15:10-11 : 10 And having called together the multitudes unto him, he said to them: Hear ye and understand. 11 Not that which goeth into the mouth defileth a man: but what cometh out of the mouth, this defileth a man.
Matthew 15:18-19 : 18 But the things which proceed out of the mouth, come forth from the heart, and those things defile a man. 19 For from the heart come forth evil thoughts, murders, adulteries, fornications, thefts, false testimonies, blasphemies.
James 1:26 : And if any man think himself to be religious, not bridling his tongue but deceiving his own heart, this man's religion is vain.
James 3:5-10 : 5 Even so the tongue is indeed a little member and boasteth great things. Behold how small a fire kindleth a great wood. 6 And the tongue is a fire, a world of iniquity. The tongue is placed among our members, which defileth the whole body and inflameth the wheel of our nativity, being set on fire by hell. 7 For every nature of beasts and of birds and of serpents and of the rest is tamed and hath been tamed, by the nature of man. 8 But the tongue no man can tame, an unquiet evil, full of deadly poison. 9 By it we bless God and the Father: and by it we curse men who are made after the likeness of God. 10 Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be.
1 Peter 3:9 : Not rendering evil for evil, nor railing for railing, but contrariwise, blessing: for unto this are you called, that you may inherit a blessing. For he that will love life and see good days, let him refrain his tongue from evil, and his lips that they speak no guile.
