Matthew 12:33-37 - Good Trees And Good Fruit Or Bad Trees And Bad Fruit
33 Either allow the tree to be good, and it's fruit good; or shew the tree to be corrupt, and it's fruit corrupt: for the tree is known by it's fruit. 34 O race of vipers, how can ye speak good things, who are yourselves so wicked? for out of the abundance of the heart the mouth speaketh. 35 A good man out of the good treasure of the heart produceth good things; and a wicked man out of the wicked treasure uttereth wicked things: 36 but I tell you, that of every idle word, which men shall speak, they shall give an account in the day of judgement; for by thy words thou shalt be justified, 37 and by thy words thou shalt be condemned.
