'Fear Not' in the Bible

And as he was revolving the matter in his mind, behold, an angel of the Lord in a dream appeared unto him, saying, Joseph, son of David, fear not to take Mary for thy wife, for that which is conceived in her is from the Holy Spirit.

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

Then the angel addressing them, said to the women, Fear not ye; for I know that ye are seeking Jesus who was crucified.
