Matthew 7:17 ASV

¹⁵  Beware of false prophets, who come to you in sheep's clothing, but inwardly are ravening wolves.

¹⁶  By their fruits ye shall know them. Do 'men' gather grapes of thorns, or figs of thistles?

¹⁷  Even so every good tree bringeth forth good fruit; but the corrupt tree bringeth forth evil fruit.

¹⁸  A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.

¹⁹  Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
