Matthew 7:15-18

King James Version

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

¹⁶ Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?

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

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