'Fear Not' in the Bible

But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, son of David, fear not to take unto you Mary your wife: for that which is conceived in her is of the Holy Spirit.

And fear not them who kill the body, but are not able to kill the soul: but rather fear him who is able to destroy both soul and body in hell.

Fear not therefore, you are of more value than many sparrows.

And the angel answered and said unto the women, Fear not: for I know that you seek Jesus, who was crucified.
