43 For a good tree does not bring forth corrupt fruit; neither does a corrupt tree bring forth good fruit. 44 For every tree is known by its own fruit. For of thorns men do not gather figs, nor of a bramble bush do they gather grapes. 45 The good man out of the good treasure of his heart brings forth that which is good, and the evil man out of the evil treasure of his heart brings forth that which is evil, for of the abundance of the heart his mouth speaks.
