Deuteronomy 28:23  (King James Version)
And thy heaven that is over thy head shall be brass, and the earth that is under thee shall be iron.

The language here is remarkable: "Thy heaven;" that part of the atmosphere which was over Judea, instead of being replenished with aqueous vapours, should become, with respect to moisture, like brass: and consequently their land would become as hard as iron, and wholly incapable of cultivation; while the clouds might give showers in abundance, and the earth be moist and fruitful in other regions.
