He sent swarms of flies among them, which devoured them; and frogs, which destroyed them.

Hippolytus of Rome
AD 235
Now, just as, in consequence of an irregular mode of living, a deadly bilious humour may be formed in the inwards, which the physician by his art may bring on to be a sick-vomiting, without being himself chargeable with producing the sick humour in the man's body; for excess in diet was what produced it, while the physician's science only made it show itself; so, although it may be said that the painful retribution that falls upon those who are by choice wicked comes from God, it would be only in accordance with right reason, to think that ills of that kind find both their beginnings and their causes in ourselves. For to one who lives without sin there is no darkness, no worm, no hell (Gehenna), no fire, nor any other of these words or things of terror; just as the plagues of Egypt were not for the Hebrews,— those fine lice annoying with invisible bites, the dog-fly fastening on the body with its painful sting, the hurricanes from heaven falling upon them with hailstones, the husbandman's labours devoured by the locusts, the darkened sky, and the rest. It is God's counsel, indeed, to tend the true vine, and to destroy the Egyptian, while sparing those who are to eat the grape of gall, and drink the deadly venom of asps. And the sycamine of Egypt is utterly destroyed; not, however, that one which Zaccheus climbed that he might be able to see my Lord. And the fruits of Egypt are wasted, that is, the works of the flesh, but not the fruit of the Spirit, love, joy, and peace.Galatians 5:22
