7 “Only be courageous and very strong, and observe carefully the entire Law that Moses my servant commanded you. Do not deviate from it either to the right or to the left,+ so that you may act wisely wherever you go.+ 8 This book of the Law should not depart from your mouth,+ and you must read it in an undertone* day and night, in order to observe carefully all that is written in it;+ for then your way will be successful and then you will act wisely.+
