Leviticus 26:16-20

16I also will do this unto you — I will even appoint over you terror, consumption, and fever, which shall cause the eyes to fail, and the soul to waste away; and ye shall sow your seed in vain, for your enemies shall eat it.

17And I will set my face against you, that ye may be routed before your enemies; they that hate you shall have dominion over you; and ye shall flee when none pursueth you.

18And if for this ye hearken not unto me, I will punish you sevenfold more for your sins,

19and I will break the arrogance of your power; and I will make your heaven as iron, and your earth as bronze,

20and your strength shall be spent in vain, and your land shall not yield its produce; and the trees of the land shall not yield their fruit.
