'Courage' in the Bible

Be of good courage, and let us play the man for our people, and for the cities of our God: and Jehovah do that which seemeth him good.

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 Jehovah God, even my God, is with thee; he will not fail thee, nor forsake thee, until all the work for the service of the house of Jehovah be finished.
