THE NINTH PLAGUE.
(21-23) The ninth plague, like the third and sixth, was sent without any previous warning. It consisted in a “thick darkness,” which may have been brought about by means of the Khamsin, or “Wind of the Desert,” which frequently blows about the time of the vernal equinox, and brings with it such clouds of a fine impalpable sand that the light of the sun is obscured, and an effect produced which some travellers have compared to “the most gloomy night.” Or it may have been a shutting out of the sun’s rays by dense fog and cloud of a more ordinary character; though in that case there must have been something in the visitation very much exceeding any known instance of such darkness. “They saw not one another,” we are told, “for three days” (Exodus 10:23). The darkness was one which “might be felt” (Exodus 10:21). Such a preternatural continuance of absolutely impenetrable “blackness of darkness” would cause to any man a feeling of intense alarm and horror. To the Egyptians it would be peculiarly painful and terrible. Ra, the sun-god, was among the principal objects of their worship, especially in the Delta, where Heliopolis and Pithoni were cities dedicated to him. Darkness was a creation of Set — the Evil Principle, the destroyer of Osiris — and of Apophis, the Great Serpent, the impeder of souls in the lower world. It would have seemed to the Egyptians that Ra was dead, that Set had triumphed over his brother, that Apophis had encircled the world with his dark folds, and plunged it in eternal night. Hence Pharaoh’s early call for Moses, and permission that the people should depart, with their families (Exodus 10:24): a concession which, however, was marred by the proviso, “Only let your flocks and herds be stayed.”
