Exodus 9:22,23

Upon man Upon those men that presumed to continue in the field after this admonition. The Lord rained hail upon the land of Egypt This was the more extraordinary, as rain seldom falls in Egypt, and in some parts of the country is scarcely known at all. And snow and hail are still more rare, the climate not being so cold as to produce them. Sometimes, however, they do fall, as is implied in the next verse, and is attested by eye-witnesses.
