Matthew 7:16

13 Enter ye in at the strait gate: for wide [is] the gate, and broad [is] the way, that leadeth to destruction, and many there be which go in thereat:

14 Because strait [is] the gate, and narrow [is] the way, which leadeth unto life, and few there be that find it.

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.

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