When all these things have happened to you, the blessings and the curses that I have set before you, if you call them to mind among all the nations where the Lord your God has driven you,
and return to the Lord your God, and you and your children obey him with all your heart and with all your soul, just as I am commanding you today,
then the Lord your God will restore your fortunes and have compassion on you, gathering you again from all the peoples among whom the Lord your God has scattered you.
Even if you are exiled to the ends of the world, from there the Lord your God will gather you, and from there he will bring you back.
