Joshua 1:7, 9

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.
