Leviticus 26:19-21

Revised Standard Version

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.

²¹ “Then if you walk contrary to me, and will not hearken to me, I will bring more plagues upon you, sevenfold as many as your sins.
