Leviticus 26:16-20

16I also will do this unto you; I will even appoint over you terror, consumption, and the burning ague, that shall consume the eyes, and cause sorrow of heart: and ye shall sow your seed in vain, for your enemies shall eat it.1

17And I will set my face against you, and ye shall be slain before your enemies: they that hate you shall reign over you; and ye shall flee when none pursueth you.

18And if ye will not yet for all this hearken unto me, then I will punish you seven times more for your sins.

19And I will break the pride of your power; and I will make your heaven as iron, and your earth as brass:

20And your strength shall be spent in vain: for your land shall not yield her increase, neither shall the trees of the land yield their fruits.
