Matthew 7:15-20 New American Standard Bible (NASB)
A Tree and Its Fruit
15 “Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves. 16 You will [a]know them by their fruits. [b]Grapes are not gathered from thorn bushes nor figs from thistles, are they? 17 So every good tree bears good fruit, but the bad tree bears bad fruit. 18 A good tree cannot produce bad fruit, nor can a bad tree produce good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 So then, you will [c]know them by their fruits.
Matthew 7:15-20 Young's Literal Translation (YLT)
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.
18 A good tree is not able to yield evil fruits, nor a bad tree to yield good fruits.
19 Every tree not yielding good fruit is cut down and is cast to fire:
20 therefore from their fruits ye shall know them.
