Behold, tomorrow about this time,.... 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 storm of hail, thunder, and lightning, and earthquakes yet to come, which will be such as has not been since men were upon the earth, with which this plague may be compared, Re 16:19, but here is meant since Egypt was inhabited, or rather formed into a kingdom, and founded as such, which had been many hundreds of years before this time; there was a king of Egypt in Abraham's time; the first founder of this empire, and king of it, was Mizraim, the son of Ham, from whom it had its name, by which it is usually called in Scripture.
