Matthew 15:11:
"Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man."
19 For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:
20 These are the things which defile a man.
12:34-36: "O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. 35 A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things. 36 But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment."
Colosians 3:8 But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.
