'Courageous' in the Bible

Be strong, be courageous on behalf of our people and for the cities of our God, and may the LORD do what he thinks is best."

Then you will be successful, if you keep on observing the statutes and ordinances that the LORD commanded Moses concerning Israel. Be strong, be courageous, and never give in to fear or dismay.

David continued with these words for his son Solomon: "Be strong and courageous, and get to work. Never be afraid or discouraged, for the LORD God, my God, is with you. He will not fail you nor will he abandon you right up to your completion of the work for the service of the Temple of the LORD.
