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.  Keep this Book of the Law always on your lips; 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 afraid; do not be discouraged, for the LORD your God will be with you wherever you go.
