Exodus 9:18

Hail - A greeting of joy and peace.

Morrow - Next day; tomorrow.

To-morrow about this time - The time of this plague is marked thus circumstantially to show Pharaoh that Jehovah was Lord of heaven and earth, and that the water, the fire, the earth, and the air, which were all objects of Egyptian idolatry, were the creatures of his power; and subservient to his will; and that, far from being able to help them, they were now, in the hands of God, instruments of their destruction.

To rain a very grievous hail - To rain hail may appear to some superficial observers as an unphilosophical mode of expression, but nothing can be more correct. "Drops of rain falling through a cold region of the atmosphere are frozen and converted into hail;" and thus the hail is produced by rain. When it begins to fall it is rain; when it is falling it is converted into hail; thus it is literally true that it rains hail. The farther a hail-stone falls the larger it generally is, because in its descent it meets with innumerable particles of water, which, becoming attached to it, are also frozen, and thus its bulk is continually increasing till it reaches the earth. In the case in question, if natural means were at all used, we may suppose a highly electrified state of an atmosphere loaded with vapors, which, becoming condensed and frozen, and having a considerable space to fall through, were of an unusually large size. Though this was a supernatural storm, there have been many of a natural kind, that have been exceedingly dreadful. A storm of hail fell near Liverpool, in Lancashire, in the year 1795, which greatly damaged the vegetation, broke windows, etc., etc. Many of the stones measured five inches in circumference. Dr. Halley mentions a similar storm of hail in Lancashire, Cheshire, etc., in 1697, April 29, that for sixty miles in length and two miles in breadth did immense damage, by splitting trees, killing fowls and all small animals, knocking down men and horses, etc., etc. Mezeray, in his History of France, says "that in Italy, in 1510, there was for some time a horrible darkness, thicker than that of night, after which the clouds broke into thunder and lightning, and there fell a shower of hail-stones which destroyed all the beasts, birds, and even fish of the country. It was attended with a strong smell of sulphur, and the stones were of a bluish color, some of them weighing one hundred pounds' weight." The Almighty says to Job: "Hast thou seen the treasures of the hail, which I have reserved against the time of trouble, against the day of battle and war?" Job 38:22, Job 38:23. While God has such artillery at his command, how soon may he desolate a country or a world! See the account of a remarkable hail-storm in Joshua 10:11.

A very grievous hail - The miracle consisted in the magnitude of the infliction and in its immediate connection with the act of Moses.

9:18 Since the foundation thereof - Since it was a kingdom.
