Deuteronomy 28:33, 51

The fruit of thy ground, and all thy labors, shall a nation which thou knowest not eat up; and thou shalt be only oppressed and crushed alway

and shall eat the fruit of thy cattle, and the fruit of thy ground, until thou be destroyed; that also shall not leave thee grain, new wine, or oil, the increase of thy cattle, or the young of thy flock, until they have caused thee to perish.
