Deuteronomy 28:31, 33

Your ox shall be slaughtered before your eyes, but you shall not eat any of it. Your donkey shall be seized before your face, but shall not be restored to you. Your sheep shall be given to your enemies, but there shall be no one to help you.

A nation that you have not known shall eat up the fruit of your ground and of all your labors, and you shall be only oppressed and crushed continually
