'Be Strong' in the Bible

Be strong and confident and courageous, for you will give this people as an inheritance the land which I swore to their fathers (ancestors) to give them.

Only be strong and very courageous; be careful to do [everything] in accordance with the entire law which Moses My servant commanded you; do not turn from it to the right or to the left, so that you may prosper and be successful wherever you go.

Have I not commanded you? Be strong and courageous! Do not be terrified or dismayed (intimidated), for the Lord your God is with you wherever you go.”

Any man who rebels against your command and does not obey everything that you command him, shall be put to death; only be strong and courageous.”

Joshua said to them, “Do not fear or be dismayed (intimidated)! Be strong and courageous, for this is what the Lord will do to all your enemies against whom you [are about to] fight.”
