Leviticus 26:17-20

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.
