frog
   heb. tsepharde'a, meaning a "marsh-leaper". this reptile is
   mentioned in the old testament only in connection with one of
   the plagues which fell on the land of egypt ex. 8:2-14; ps.
   78:45; 105:30.
   
     in the new testament this word occurs only in rev. 16:13,
   where it is referred to as a symbol of uncleanness. the only
   species of frog existing in palestine is the green frog rana
   esculenta, the well-known edible frog of the continent.
   

[7] : THE DEVIL'S DICTIONARY ((C)1911 Released April 15 1993)

frog, n.  a reptile with edible legs.  the first mention of frogs in
profane literature is in homer's narrative of the war between them and
the mice.  skeptical persons have doubted homer's authorship of the
work, but the learned, ingenious and industrious dr. schliemann has
set the question forever at rest by uncovering the bones of the slain
frogs.  one of the forms of moral suasion by which pharaoh was
besought to favor the israelities was a plague of frogs, but pharaoh,
who liked them _fricasees_, remarked, with truly oriental stoicism,
that he could stand it as long as the frogs and the jews could; so the
programme was changed.  the frog is a diligent songster, having a good
voice but no ear.  the libretto of his favorite opera, as written by
aristophanes, is brief, simple and effective -- "brekekex-koax"; the
music is apparently by that eminent composer, richard wagner.  horses
have a frog in each hoof -- a thoughtful provision of nature, enabling
them to shine in a hurdle race.
