16Today, the Lord your God commands you to obey these laws and these rules. So be careful to obey them with all your mind and with all your strength.

17Today, you have said clearly that the Lord is your God. You have agreed to live in a way that pleases him. You have agreed that you will obey his rules, his commands and his laws. You will do everything that he has told you to do.
