Then shall you prosper, if you observe to do the statutes and the ordinances which the LORD gave Moshe concerning Yisra'el. Be strong, and of good courage. Don't be afraid, neither be dismayed.
David said to Shlomo his son, Be strong and of good courage, and do it: don't be afraid, nor be dismayed; for the LORD God, even my God, is with you; he will not fail you, nor forsake you, until all the work for the service of the house of the LORD is finished.
