He spake, and there came divers sorts of flies
Or a "mixture" F26 of various insects, and, as some interpret it, of wild beasts; and so Kimchi says evil beasts are meant, which were raised up to go into all their borders; the Arabic version renders it "dogflies", after the Septuagint; (See Gill on Psalms 78:45), this was the fourth plague, ( Exodus 8:24 ) .
And lice in all their coasts;
this is the third plague, and what the magicians could not imitate, but were obliged to own the finger of God was in it, ( Exodus 8:16-19 ) . God can make use of mean and despicable instruments to do his work; the weakness of God is stronger than men.
