Exodus 9:18

“Behold, tomorrow about this time, etc.] It was now the fourth day of the month Abib, and the fifth when the following was inflicted: I will cause it to rain a very grievous hail; which should fall very thick, and the hailstones be very numerous and heavy, and the storm last long: such as hath not been in Egypt since the foundation thereof, even until now; not since the earth or land itself was founded, for that was founded when the rest of the world was, and the sense then would be the same as since the foundation of the world; and so the Targum of Jonathan seems to understand it, paraphrasing the words, “from the day that men were made, even until now.” And a like expression is used of a…”

“PLAGUE OF HAIL. (Exo. 9:18-35) I will cause it to rain a very grievous hail, &c.--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 of immense size fell, thunder pealed in awful volleys, and lightning swept the ground…”

Exodus 9:14 All my plagues - This applies to all the plagues which follow; the effect of each was foreseen and foretold. The words “at this time” point to a rapid and continuous succession of blows. The plagues which precede appear to have been spread over a considerable time; the first message of Moses was delivered after the early harvest of the year before, when the Israelites could gather stubble, i. e. in May and April: the second mission, when the plagues began, was probably toward the end of…”

“Since the foundation thereof - Since it was a kingdom. Exodus 9:29”

“to morrow: Kg1 19:2, Kg1 20:6; Kg2 7:1, Kg2 7:18 I will cause: This must have been a circumstance of all others the most incredible to an Egyptian; for in Egypt there fell no rain, the want of which was supplied by dews, and the overflowing of the Nile. The Egyptians must, therefore, have perceived themselves particularly aimed at in these fearful events, especially as they were very superstitious. There seems likewise a propriety in their being punished by fire and water, as they were guilty of the grossest idolatry towards these elements. Scarcely anything could have distressed the Egyptians more than the destruction of the flax, as the whole nation wore linen garments. The ruin of their…”
