Matthew 7:15-20

15 Be ye ware of false prophets, that come to you in clothings of sheep, but withinforth they be wolves of raven; [+Perceive, or beware, ye, and flee from false prophets, which come to you in clothing of sheep, but within they be snatching wolves;]

16 of their fruits ye shall know them. Whether men gather grapes of thorns, or figs of briers?

17 So every good tree maketh good fruits; but an evil tree maketh evil fruits.

18 A good tree may not make evil fruits, neither an evil tree [may] make good fruits.

19 Every tree that maketh not good fruit, shall be cut down, and shall be cast into the fire.

20 Therefore of their fruits ye shall know them.
