Either make the tree good, and its fruit good; or else make the tree corrupt, and its fruit corrupt: for the tree is known by its fruit.

Even so every good tree brings forth good fruit; but a corrupt tree brings forth evil fruit.

A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.

And when he saw a fig tree in the way, he came to it, and found nothing thereon, but leaves only, and said unto it, Let no fruit grow on you again forever. And presently the fig tree withered away.

And now also the ax is laid unto the root of the trees: therefore every tree which brings not forth good fruit is hewn down, and cast into the fire.
