Leviticus 26:17-21

And 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.

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

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

And 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.

And if ye walk contrary unto me, and will not hearken unto me; I will bring seven times more plagues upon you according to your sins.
