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

So every good tree produces good fruits; and a corrupt tree produces evil fruits.

A good tree is not able to produce evil fruits, neither is a corrupt tree able to produce beautiful fruits.

And seeing one fig-tree near the road, He went to it, and found nothing on it, except leaves only. And He says to it, Let no fruit ever be from thee; and immediately the fig-tree withered away.

But already the ax is laid to the root of the trees; therefore every tree not producing good fruit is hewn down and cast into the fire.
