Leviticus 26:18-21

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.

²¹And if after this ye should walk perversely, and not be willing to obey me, I will further bring upon you seven plagues according to your sins.
