'Thorns' in the Bible

Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?

And some fell among thorns; and the thorns sprung up, and choked them:

He also that received seed among the thorns is he that heareth the word; and the care of this world, and the deceitfulness of riches, choke the word, and he becometh unfruitful.

And when they had platted a crown of thorns, they put it upon his head, and a reed in his right hand: and they bowed the knee before him, and mocked him, saying, Hail, King of the Jews!
