Deuteronomy 28:45-48

And all these curses will come after you and overtake you, till your destruction is complete; because you did not give ear to the voice of the Lord your God, or keep his laws and his orders which he gave you: These things will come on you and on your seed, to be a sign and a wonder for ever; Because you did not give honour to the Lord your God, worshipping him gladly, with joy in your hearts on account of all your wealth of good things; For this cause you will become servants to those whom the Lord your God will send against you, without food and drink and clothing, and in need of all things: and he will put a yoke of iron on your neck till he has put an end to you.
