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; Ps 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.
