Leviticus 26:18-20

Young's Literal Translation

¹⁸ `And if unto these ye hearken not to Me, -- then I have added to chastise you seven times for your sins;

¹⁹ and I have broken the pride of your strength, and have made your heavens as iron, and your earth as brass;

²⁰ and consumed hath been your strength in vain, and your land doth not give her produce, and the tree of the land doth not give its fruit.
