Deuteronomy 28:22-24
weakness <07829> [a consumption.]
sword <02719> [sword. or, drought. blasting.]
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.
will make ... rain <04306 05414> [make the rain.]
This was a natural consequence of their heaven's being brass, or yielding no rain; for the surface of the earth being reduced to powder, and frequently taken up by strong winds, would fall down in showers instead of rain. These showers of sand frequently, in the East, bury whole caravans.
