Behold, tomorrow at about this time, I will cause it to rain a very severe hailstorm, the likes of which has not occurred in Egypt since the day it was founded until now.
Adonai will make His glorious voice heard, and reveal His arm descending with fierce fury in a consuming fire, in cloudburst, rainstorm and hailstones.
Say to those who plaster it over with whitewash, that it will fall. There will be a down-pouring rain, and on you great hailstones will fall, and a storm wind will break out.
Therefore thus says Adonai Elohim: “I will cause a storm wind to burst out in My fury. There will be a down-pouring rain in My anger and great hailstones in destructive wrath.
While they were fleeing before Israel down the descent of Beth-horon, Adonai cast down great stones from heaven on them all the way to Azekah so they died—more of them died from the hailstones than those Bnei-Yisrael killed with the sword.
Enormous hail—about a hundred pounds each—falls from heaven on the people. And the people cursed God because of the plague of hail—so extreme was that plague.
