This book of the law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it; for then you will make your way prosperous, and then you will have success.
if you obey the Lord your God to keep His commandments and His statutes which are written in this book of the law, if you turn to the Lord your God with all your heart and soul.
