'Do Not Fear' in the Bible

then thou dost prosper, if thou dost observe to do the statutes and the judgments that Jehovah charged Moses with concerning Israel; be strong and courageous; do not fear, nor be cast down.

And David saith to Solomon his son, 'Be strong, and courageous, and do; do not fear nor be affrighted, for Jehovah God, my God, is with thee; He doth not fail thee, nor forsake thee, unto the completion of all the work of the service of the house of Jehovah.
