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.
The hail fell very severely, with fire flashing up amidst the hail, the likes of which had not occurred in all the land of Egypt since it became a nation.
Adonai will make His glorious voice heard, and reveal His arm descending with fierce fury in a consuming fire, in cloudburst, rainstorm and hailstones.
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.
