Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.

Ye shall know them by their fruits. Do men gather grapes of thorns, or

figs of thistles?

Even so every good tree bringeth forth good fruit; but a corrupt tree

bringeth forth evil fruit.

A good tree cannot bring forth evil fruit, neither can a corrupt tree

bring forth good fruit. 

Every tree that bringeth not forth good fruit is hewn down, and cast

into fire.

Wherefore by their fruits ye shall know them. Matthew 7:15-20
