假先知

¹⁵ “Beware of false prophets who come disguised as harmless sheep but are really vicious wolves. ¹⁶You can identify them by their fruit, that is, by the way they act. Can you pick grapes from thornbushes, or figs from thistles? ¹⁷A good tree produces good fruit, and a bad tree produces bad fruit. ¹⁸A good tree can’t produce bad fruit, and a bad tree can’t produce good fruit. ¹⁹So every tree that does not produce good fruit is chopped down and thrown into the fire. ²⁰Yes, just as you can identify a tree by its fruit, so you can identify people by their actions.
