By their fruits ye shall know them. Do (men) gather grapes of thorns, or figs of thistles?
Even so every good tree bringeth forth good fruit; but the 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 the fire.
Therefore by their fruits ye shall know them.
