'Be Not Afraid' in the Bible

But the angel said unto them, "Be not afraid: For behold, I bring you tidings of great joy, that shall come to all the people:

I say unto you my friends, Be not afraid of them that kill the body, and after that have no more that they can do.

But when ye hear of war, and of dissension: be not afraid, for these things must first come: but the end followeth not by and by."
