Deuteronomy 28:27-35

27“The Lord will strike you with the boils of Egypt and with tumors and with the scab and the itch that you cannot heal.

28The Lord will strike you with madness and with blindness and with bewilderment of heart and mind;

29and you will be groping at noon [in broad daylight], just as the blind grope in the darkness, and nothing you do will prosper; but you will only be oppressed and exploited and robbed continually, with no one to save you.

30You will be pledged to marry a wife, but another man will be intimate with her [before you]; you will build a house, but you will not live in it; you will plant a vineyard, but you will not use its fruit.

31Your ox will be slaughtered before your eyes, but you will not eat any of it; your donkey will be torn away from you, and it will not be returned to you; your sheep will be given to your enemies, and you will have no one to save you.

32Your sons and daughters will be given to another people, while your eyes look on and long for them continually; but there will be nothing you can do.

33A people whom you do not know will eat the produce of your land and all the products of your labors, and you will never be anything but oppressed and exploited and crushed continually.

34You shall be driven mad by the sight of the things you see.

35The Lord will strike you on the knees and on the legs with sore boils that you cannot heal, from the sole of your foot to the crown of your head.
