'Thorn' in the Bible

Other seed fell among thorns, and the thorns came up and choked it, and it yielded no grain.

And others are the ones sown among the thorn plants--these are the ones who hear the word,

But as to the dead coming back to life; have you not seen in the book of Moses, about the burning thorn-tree, how God said to him, I am the God of Abraham, and the God of Isaac, and the God of Jacob?
