Matthew 7:15-17

Young's Literal Translation

¹⁵ `But, take heed of the false prophets, who come unto you in sheep's clothing, and inwardly are ravening wolves.

¹⁶ From their fruits ye shall know them; do [men] gather from thorns grapes? or from thistles figs?

¹⁷ so every good tree doth yield good fruits, but the bad tree doth yield evil fruits.
