Lice
(Heb. kinnim), the creatures employed in the third plague sent
upon Egypt (Ex. 8:16-18). They were miraculously produced from
the dust of the land. "The entomologists Kirby and Spence place
these minute but disgusting insects in the very front rank of
those which inflict injury upon man. A terrible list of examples
they have collected of the ravages of this and closely allied
parasitic pests." The plague of lice is referred to in Ps.
105:31.
Some have supposed that the word denotes not lice properly,
but gnats. Others, with greater probability, take it to mean the
"tick" which is much larger than lice.
