'Thorn bush' in the Bible

And the Angel of Jehovah appeared to him in a flame of fire, out of the midst of a thorn bush. And he looked. And behold! The thorn bush burned with fire! And the thorn bush was not burned up.

And Moses said, I will now turn aside and see this great sight, why the thorn bush is not burned up.

And Jehovah saw that he had turned aside to see. God called to him out of the midst of the thorn bush, and said, Moses! Moses! And he said, Here I am.
