Matthew 7:15-20 King James Version (KJV)
15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
20 Wherefore by their fruits ye shall know them.
Matthew 7:15-20 Living Bible (TLB)
15 “Beware of false teachers who come disguised as harmless sheep, but are wolves and will tear you apart. 16 You can detect them by the way they act, just as you can identify a tree by its fruit. You need never confuse grapevines with thorn bushes or figs with thistles. 17 Different kinds of fruit trees can quickly be identified by examining their fruit. 18 A variety that produces delicious fruit never produces an inedible kind. And a tree producing an inedible kind can’t produce what is good. 19 So the trees having the inedible fruit are chopped down and thrown on the fire. 20 Yes, the way to identify a tree or a person[a] is by the kind of fruit produced.
Matthew 7:15-20 Amplified Bible (AMP)
A Tree and Its Fruit
15 “Beware of the false prophets, [teachers] who come to you dressed as sheep [appearing gentle and innocent], but inwardly are ravenous wolves. 16 By their fruit you will recognize them [that is, by their contrived doctrine and self-focus]. Do people pick grapes from thorn bushes or figs from thistles? 17 Even so, every healthy tree bears good fruit, but the unhealthy tree bears bad fruit. 18 A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Therefore, by their fruit you will recognize them [as false prophets].
