'Be Strong' in the Bible

Be strong and of good courage; for thou shalt cause this people to inherit the land which I sware unto their fathers to give them.

Only be strong and very courageous, to observe to do according to all the law, which Moses my servant commanded thee: turn not from it to the right hand or to the left, that thou mayest have good success whithersoever thou goest.

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

Whosoever he be that shall rebel against thy commandment, and shall not hearken unto thy words in all that thou commandest him, he shall be put to death: only be strong and of good courage.

And Joshua said unto them, Fear not, nor be dismayed; be strong and of good courage: for thus shall Jehovah do to all your enemies against whom ye fight.
