Deuteronomy 28:33, 51

A people whom you do not know will eat the produce of your land and all the products of your labors, and you will never be anything but oppressed and exploited and crushed continually. [Judg 6:1-6; 13:1]

and it will eat the offspring of your herd and the produce of your ground until you are destroyed, who will leave you no grain, new wine, or oil, nor the offspring of your herd or the young of your flock until they have caused you to perish.
