Luke 6:43-45

43For a good tree bringeth not forth corrupt fruit; neither doth a corrupt tree bring forth good fruit. 44For every tree is known by its own fruit. For from thorns men do not gather figs, nor from a bramble bush do they gather grapes.1 45A 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 from the abundance of the heart his mouth speaketh.
