For each tree is known by its own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes.
can a fig tree, my brethren, yield olives, or a vine figs? neither can salt water yield sweet.
Either make the tree good, and its fruit good; or make the tree corrupt, and its fruit corrupt: for the tree is known by its fruit.
These are they who are hidden rocks in your love-feasts when they feast with you, shepherds that without fear feed themselves; clouds without water, carried along by winds; autumn trees without fruit, twice dead, plucked up by the roots;
By their fruits ye shall know them. Do men gather grapes of thorns, or figs of thistles?
Therefore by their fruits ye shall know them.
