'Be Strong' in the Bible

Be strong, and let us show ourselves courageous for the sake of our people and for the cities of our God; and may the Lord do what is good in His sight.”

Then you will prosper, if you are careful to observe the statutes and the ordinances which the Lord commanded Moses concerning Israel. Be strong and courageous, do not fear nor be dismayed.

Then David said to his son Solomon, “Be strong and courageous, and act; do not fear nor be dismayed, for the Lord God, 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.
