'Thorns' in the Bible

for each tree is known by its own fruit. For figs are not gathered from thorns, nor are grapes picked from brambles.

Other seed fell among the thorns, and they grew up with it and choked it.

As for the seed that fell among thorns, these are the ones who hear, but as they go on their way they are choked by the worries and riches and pleasures of life, and their fruit does not mature.
