'Thorns' in the Bible

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.

And some fell among thorns; and the thorns sprang up with it, and choked it.

And that which fell among thorns are they, which, when they have heard, go forth, and are choked with cares and riches and pleasures of this life, and bring no fruit to perfection.
