Deuteronomy 28:45-48

All these curses will come on you. They will pursue you and overtake you until you are destroyed, because you did not obey the LORD your God and observe the commands and decrees he gave you. They will be a sign and a wonder to you and your descendants forever. Because you did not serve the LORD your God joyfully and gladly in the time of prosperity, therefore in hunger and thirst, in nakedness and dire poverty, you will serve the enemies the LORD sends against you. He will put an iron yoke on your neck until he has destroyed you.
