'Be Strong' in the Bible

Be strong and courageous, for you shall give this people possession of the land which I swore to their fathers to give them.

Only be strong and very courageous; be careful to do according to all the law which Moses My servant commanded you; do not turn from it to the right or to the left, so that you may have success wherever you go.

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

Anyone who rebels against your command and does not obey your words in all that you command him, shall be put to death; only be strong and courageous.”

Joshua then said to them, “Do not fear or be dismayed! Be strong and courageous, for thus the Lord will do to all your enemies with whom you fight.”
