Matthew 7:16-20

¹⁶By their fruits ye shall know them. Do [men] gather grapes of thorns, or figs of thistles? ¹⁷Even so every good tree bringeth forth good fruit; but the corrupt tree bringeth forth evil fruit. ¹⁸A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. ¹⁹Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. ²⁰Therefore by their fruits ye shall know them.
