Deuteronomy 28:30-31, 33

“You will be engaged to a woman, but another man will sleep with her. You will build a house, but someone else will live in it. You will plant a vineyard, but you will never enjoy its fruit. Your ox will be butchered before your eyes, but you will not eat a single bite of the meat. Your donkey will be taken from you, never to be returned. Your sheep and goats will be given to your enemies, and no one will be there to help you.

A foreign nation you have never heard about will eat the crops you worked so hard to grow. You will suffer under constant oppression and harsh treatment.
