'Thorn bushes' in the Bible

For each tree is known by its own fruit. Figs aren’t gathered from thornbushes, or grapes picked from a bramble bush.

Others fell among thorn bushes, and the thorn bushes grew with them and choked them.

The ones that fell among the thorn bushes are the people who listen, but as they go on their way they are choked by the worries, wealth, and pleasures of life, and their fruit doesn't mature.
