Leviticus 26:17-20

¹⁷And I will set my face against you, and ye shall fall before your enemies, and they that hate you shall pursue you; and ye shall flee, no one pursuing you.

¹⁸And if ye still refuse to hearken to me, then will I chasten you yet more even seven times for your sins.

¹⁹And I will break down the haughtiness of your pride; and I will make your heaven iron, and your earth as it were brass.

²⁰And your strength shall be in vain; and your land shall not yield its seed, and the tree of your field shall not yield its fruit.
