“Be strong and courageous, because you will lead these people to inherit the land I swore to their forefathers to give them. Be strong and very courageous.
Be careful to obey all the law my servant Moses gave you; do not turn from it to the right or to the left, that you may be successful wherever you go.
Do not let this Book of the Law depart from your mouth; meditate on it day and night, so that you may be careful to do everything written in it. Then you will be prosperous and successful.
Have I not commanded you? Be strong and courageous. Do not be terrified; do not be discouraged, for the LORD your God will be with you wherever you go.”
Joshua 1:6-9 (NIV)
