'Courageous' in the Bible

Then you will succeed if you carefully follow the statutes and ordinances the Lord commanded Moses for Israel. Be strong and courageous. Don’t be afraid or discouraged.

Then David said to his son Solomon, “Be strong and courageous, and do the work. Don’t be afraid or discouraged, for the Lord God, my God, is with you. He won’t leave you or forsake you until all the work for the service of the Lord’s house is finished.
