Deuteronomy 28:33-35

Revised Standard Version

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.
