Deuteronomy 28:33

33 A nation which 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;

Deuteronomy 28:33 In-Context

31 Your ox shall be slain before your eyes, and you shall not eat of it; your ass shall be violently taken away before your face, and shall not be restored to you; your sheep shall be given to your enemies, and there shall be no one to help you.
32 Your sons and your daughters shall be given to another people, while your eyes look on and fail with longing for them all the day; and it shall not be in the power of your hand to prevent it.
33 A nation which 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;
34 so that you shall be driven mad by the sight which your eyes shall see.
35 The LORD will smite you on the knees and on the legs with grievous boils of which you cannot be healed, from the sole of your foot to the crown of your head.
