For a good tree bringeth not forth corrupt fruit; neither doth a corrupt tree bring forth good fruit.

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

For every tree is known by his own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes.

He spake also this parable; A certain man had a fig tree planted in his vineyard; and he came and sought fruit thereon, and found none.

Then said he unto the dresser of his vineyard, Behold, these three years I come seeking fruit on this fig tree, and find none: cut it down; why cumbereth it the ground?
