'Fear Not' in the Bible

And Jehovah said unto Joshua, Fear not, neither be thou dismayed: take all the people of war with thee, and arise, go up to Ai; see, I have given into thy hand the king of Ai, and his people, and his city, and his land;

And Joshua said unto them, Fear not, nor be dismayed; be strong and of good courage: for thus shall Jehovah do to all your enemies against whom ye fight.
