Only be strong and very courageous, being careful to do according to all the law which Moses my servant commanded you; turn not from it to the right hand or to the left, that you may have good success wherever you go.
This book of the law shall not depart out of your mouth, but you shall meditate on it day and night, that you may be careful to do according to all that is written in it; for then you shall make your way prosperous, and then you shall have good success.
