'Be Strong' in the Bible

Be strong and courageous, for thou shalt cause this people to inherit the land which I have sworn unto their fathers to give them.

Only be strong and very courageous, that thou mayest take heed to do according to all the law that Moses my servant commanded thee. Turn not from it to the right or to the left, that thou mayest prosper whithersoever thou goest.

Have I not commanded thee: Be strong and courageous? Be not afraid, neither be dismayed; for Jehovah thy God is with thee whithersoever thou goest.

Every one that is rebellious against thy commandment and hearkeneth not to thy words in everything that thou commandest us, shall be put to death. Only be strong and courageous.

And Joshua said to them, Fear not, neither be dismayed; be strong and courageous, for thus will Jehovah do to all your enemies against whom ye fight.
