Deuteronomy 28
32 Ref Your sons and your daughters shall be given to another people; and your eyes shall look, and fail with longing for them all the day: and there shall be nothing in the power of your hand.
33 Ref The fruit of your ground, and all your labors, shall a nation which you don't know eat up; and you shall be only oppressed and crushed always;
34 Ref so that you shall be mad for the sight of your eyes which you shall see.
