O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.
A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.
But those things which proceed out of the mouth come forth from the heart; and they defile the man.
