'Bush' in the Bible

and there appeareth unto him a messenger of Jehovah in a flame of fire, out of the midst of the bush, and he seeth, and lo, the bush is burning with fire, and the bush is not consumed.

And Moses saith, 'Let me turn aside, I pray thee, and I see this great appearance; wherefore is the bush not burned?'

and Jehovah seeth that he hath turned aside to see, and God calleth unto him out of the midst of the bush, and saith, 'Moses, Moses;' and he saith, 'Here am I.'
