Why by their fruits you shall know them.
Either make the tree good, and his fruit good; or else make the tree corrupt, and his fruit corrupt: for the tree is known by his fruit.
You shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
For every tree is known by his own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes.
And now I say to you, Refrain from these men, and let them alone: for if this counsel or this work be of men, it will come to nothing:
Can the fig tree, my brothers, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh.
