Matthew 12:33-35

MKJV(i) 33 Either make the tree good and its fruit good, or else make the tree corrupt and its fruit corrupt; for the tree is known by its fruit. 34 Offspring of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks. 35 A good man out of the good treasure of the heart brings out good things; and an evil man out of the evil treasure brings out evil things.
