出埃及記 8:5,17
耶和華曉諭摩西說：「你對亞倫說：『把你的杖伸在江、河、池以上，使青蛙到埃及地上來。』」…

lice.

1. they sprang from the dust, and not from the waters;

2. they were on both man and beast, which cannot be said of gnats;

3. their name is derived from koon, to make firm, fix, establish, which cannot agree with gnats, flies, which are ever changing place, and almost constantly on the wing;

4. the term kinnah is used by the Talmudists to express the louse. This insect must have been a very dreadful and afflicting plague to the Egyptians, and especially to the priests, who were obliged to shave all their hair off, and to wear a single linen tunic, to prevent vermin harbouring about them.
