'Fear Not' in the Bible

Then shalt thou prosper, if thou observe to do the statutes and the ordinances which Jehovah charged Moses with concerning Israel: be strong, and of good courage; fear not, neither be dismayed.

And David said to Solomon his son, Be strong and of good courage, and do it: fear not, nor be dismayed: for the LORD God, even my God, will be with thee; he will not fail thee, nor forsake thee, until thou hast finished all the work for the service of the house of the LORD.
