He must keep it with him and read it his entire life. He will learn to fear the Lord his God and faithfully obey everything found in these teachings and laws.
Never forget the day you stood in front of the Lord your God at Mount Horeb. The Lord had said to me, “Assemble the people in front of me, and I will let them hear my words. Then they will learn to fear me as long as they live on earth, and they will teach their children the same thing.”
However, be careful, and watch yourselves closely so that you don’t forget the things which you have seen with your own eyes. Don’t let them fade from your memory as long as you live. Teach them to your children and grandchildren.
Never stop reciting these teachings. You must think about them night and day so that you will faithfully do everything written in them. Only then will you prosper and succeed.
