Leviticus 26:18-20

American Standard Version

¹⁸ And if ye will not yet for these things hearken unto me, then I will chastise you seven times more for your sins. ¹⁹ And I will break the pride of your power: and I will make your heaven as iron, and your earth as brass; ²⁰ and your strength shall be spent in vain; for your land shall not yield its increase, neither shall the trees of the land yield their fruit.
