Source: Nav
Leviticus 26:18–21
And if after all this you will not obey Me, I will proceed to punish you sevenfold for your sins. / I will break down your stubborn pride and make your sky like iron and your land like bronze, / and your strength will be spent in vain. For your land will not yield its produce, and the trees of the land will not bear their fruit.
