Leviticus 26:18-21

¹⁸And if yet with these ye will not obey My Word, I will add sevenfold chastisement upon your sins.

¹⁹And I will break the glory of your power, and will make the heavens above you obdurate as iron, to give no rain, and the ground beneath you hard as brass in yielding no fruit;

²⁰And your strength shall be put forth in vain, for your ground will not yield its produce, nor the tree of the earth its fruit.

²¹And if you will walk on forwardly before Me, and will not turn again to obey My Word, I will add to bring upon you a stroke sevenfold (heavier) according to your sins.
