'Fear Not' in the Bible

And LORD said to 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 to them, Fear not, nor be dismayed. Be strong and of good courage, for thus shall LORD do to all your enemies against whom ye fight.
