Above all, be strong and very courageous to carefully observe the whole instruction My servant Moses commanded you. Do not turn from it to the right or the left, so that you will have success wherever you go.
This book of instruction must not depart from your mouth; you are to recite it day and night, so that you may carefully observe everything written in it. For then you will prosper and succeed in whatever you do.
Haven't I commanded you: be strong and courageous? Do not be afraid or discouraged, for the Lord your God is with you wherever you go."
