Either make the tree good, and its fruit good; or make the tree unsound, and its fruit unsound. For by the fruit the tree is known.

and seeing a fig-tree on the road, he went to it, and found nothing on it but leaves; and he said to it: Let no fruit grow on you henceforth forever. And the fig-tree immediately withered.

So every good tree produces goodly fruit: but an unsound tree produces diseased fruit.

A good tree can not produce diseased fruit; nor can an unsound tree produce goodly fruit.

Even now the ax is lying at the root of the trees: therefore, every tree that does not bring forth good fruit is cut down and thrown into the fire.
