Leviticus 26:18-20

Revised Standard Version

¹⁸ And if in spite of this you will not hearken to me, then I will chastise you again sevenfold for your sins, ¹⁹ and I will break the pride of your power, and I will make your heavens like iron and your earth like brass; ²⁰ and your strength shall be spent in vain, for your land shall not yield its increase, and the trees of the land shall not yield their fruit.
