Leviticus 26:14-16 NIV

[14] “ ‘But if you will not listen to me and carry out all these commands, [15] and if you reject my decrees and abhor my laws and fail to carry out all my commands and so violate my covenant, [16] then I will do this to you: I will bring on you sudden terror, wasting diseases and fever that will destroy your sight and sap your strength. You will plant seed in vain, because your enemies will eat it.
