“Beware of false prophets, who come to you in sheep's clothing, but inwardly are ravening wolves. By their fruits you shall know them. Do men gather grapes of thorns, or figs of thistles? Even so every good tree brings forth good fruit; but the corrupt tree brings forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Every tree that brings not forth good fruit is hewn down, and cast into the fire. Therefore by their fruits you shall know them.”
