Deuteronomy 28:33 in the King James Version
The fruit of thy land, and all thy labours, shall a nation which thou knowest not eat up; and thou shalt be only oppressed and crushed alway:
Context
32 Your sons and your daughters will be given to another people. Your eyes will look and fail with longing for them all day long. There will be no power in your hand.
33 A nation which you don’t know will eat the fruit of your ground and all of your work. You will only be oppressed and crushed always,
34 so that the sights that you see with your eyes will drive you mad.
