Be careful of false prophets. They come to you and look {gentle} like sheep. But they are really dangerous {like} wolves. You will know these people because of the things they do. Good things don't come from bad people, the same as grapes don't come from thorn bushes. And figs don't come from thorny weeds. In the same way, every good tree makes good fruit. And bad trees make bad fruit. A good tree cannot make bad fruit. And a bad tree cannot make good fruit. Every tree that does not make good fruit is cut down and thrown into the fire. You will know these false people by the fruit they make (things they do).

 — Jesus, Matthew 7:15-20 ERV
