For there is no good tree that bringeth forth corrupt fruit; nor again a corrupt tree that bringeth forth good fruit.

And he spake to them a parable: Behold the fig tree, and all the trees:

And even now the axe also lieth at the root of the trees: every tree therefore that bringeth not forth good fruit is hewn down, and cast into the fire.

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.
