Exodus 8:24

Verse Exodus 8:24. The land was corrupted] Every thing was spoiled, and many of the inhabitants destroyed, being probably stung to death by these venomous insects. This seems to be intimated by the psalmist, "He sent divers sorts of flies among them, which DEVOURED them," Psalms 78:45.

In ancient times, when political, domestic, and personal cleanliness was but little attended to, and offal of different kinds permitted to corrupt in the streets and breed vermin, flies multiplied exceedingly, so that we read in ancient authors of whole districts being laid waste by them; hence different people had deities, whose office it was to defend them against flies. Among these we may reckon Baalzebub, the fly-god of Ekron; Hercules, muscarum abactor, Hercules, the expeller of flies, of the Romans; the Muagrus of the Eleans, whom they invoked against pestilential swarms of flies; and hence Jupiter, the supreme god of the heathens, had the epithets of Απομυιος and Μυωδης, because he was supposed to expel flies, and defend his worshippers against them.
