This is what will happen: Just as the Lord delighted to do good for you and make you numerous, he ¹  will take delight in destroying and decimating you. You will be uprooted from the land you are about to possess.

What ¹  I am commanding you today is to love the Lord your God, to walk in his ways, and to obey his commandments, his statutes, and his ordinances. Then you will live and become numerous and the Lord your God will bless you in the land which you are about to possess. ² 

I declare to you this very day that you will certainly ¹  perish! You will not extend your time in the land you are crossing the Jordan to possess. ² 

Then their children, who have not known this law, ¹  will also hear about and learn to fear the Lord your God for as long as you live in the land you are crossing the Jordan to possess.”

For this is no idle word for you – it is your life! By this word you will live a long time in the land you are about to cross the Jordan to possess.”
