THE THIRD PLAGUE. (16, 17)
It is disputed whether this plague was one of lice or of mosquitoes. Josephus and the Jewish commentators generally take the former view, while the latter is supported by the LXX. and Vulgate, by the authorities of Philo, Artapanus, Origen, and St. Augustine in ancient, and by those of Rosenmüller, Michaelis, Œdmann, Gesenius, Keil, and Kalisch in modern times. The word used (kinnim) seems connected with the Greek κίνψ, or κώνωψ, and is reasonably regarded as formed by onomatopoeia, from the sharp tingling sound given out by the insect when on the wing.[58] The trouble caused to the Egyptians of the Delta by mosquitoes is noticed by Herodotus (ii. 95); while moderns, as Forskal (Descript. Anim. p. 85), declare that they amount to an absolute pest at certain seasons. They are most troublesome towards October, and are said to attack not only the exposed parts of the skin, but especially the ears, the nostrils, and the eyes, where they do great damage. Some have thought that mosquitoes do not molest cattle (Exodus 8:17); but Kalisch says, “They molest especially beasts, as oxen and horses, flying into their eyes and nostrils, driving them to madness and fury, and sometimes even torturing them to death.”
[58] In Egyptian the word for “mosquito” is Khnemms, (Brugsch, Diet. Hierogl. p. 1103).
It is to be noticed that the third plague, whatever it was, came without warning. It was God’s judgment on Pharaoh for hardening his heart and breaking his promise (Exodus 8:15); and he was not given the option of avoiding it by submission to God’s will.
(16) Smite the dust of the land. — Dust prevails in Egypt to an extent that is highly inconvenient. “We travelled to Ashmim.” says one writer, “through clouds of dust, raised by a high wind, which intercepted our view as much as if we had been travelling in a fog.” “There is one great source of discomfort,” says another, “arising from the dryness of the atmosphere, namely, an excessive quantity of dust.” When “all the dust of the land became mosquitoes” (Exodus 8:17), the plague must indeed have been great.
