Matthew 12:33-35

33 Either make the tree good, and his fruit good: or else make the tree evil, and his fruit evil: for the tree is known by the fruit.

34 [11]O generations of vipers, how can you speak good things, when ye are evil? For of the ⓛabundance of the heart the mouth speaketh.

35 A good man out of the good treasure of his heart bringeth forth good things: and an evil man out of an evil treasure, bringeth forth evil things.
