Behold, to morrow about this time I will cause it to rain a very grievous hail, such as hath not been in Egypt since the foundation thereof even until now.
I will cause it to rain ... The seventh plague which Pharaoh's hardened heart provoked was that of hail-a phenomenon which must have produced the greatest astonishment and consternation in Egypt, as rain and hailstones, accompanied by thunder and lightning were very rare occurrences.
Such as hath not been in Egypt. In the Delta, or Lower Egypt, where the scene is laid, rain occasionally falls between January and March; hail is not unknown, and thunder sometimes heard. But a storm not only exhibiting all these elements, but so terrific that hailstones fell of immense size, thunder pealed in awful volleys, and lightning swept the ground like fire, was an unexampled calamity.
