Exodus 8:24

(24) The land was corrupted.—Rather, as in the margin, destroyed. Kalisch observes, “These insects”—i.e., the kakerlaque (Blatta Orientalis), “really fill the land, and molest men and beasts; they consume all sorts of materials, devastate the country, and are in so far more detrimental than the gnats, as they destroy also the property of the Egyptians.”
