Frog - (Easton's Bible Dictionary)
(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.

(tsephardea`; compare Arabic dafda` (Ex 8:2 ff; Ps 78:45; 105:30); batrachos (Re 16:13)): The references in Psalms, as well as in Exodus, are to the plague of flogs. In Re 16:13 we have, "And I saw coming out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet, three unclean spirits, as it were frogs." The word tsephardea` probably referred both to frogs and to toads, as does the Arabic dafda`. In Palestine and Syria Rana esculenta, Bufo viridis and Hyla arborea are common. According to Mr. Michael J. Nicoll, assistant director of the Zoological Gardens at Gizah, near Cairo, the commonest Egyptian species are Rana mascariensis and Bufo regularis. Rana esculenta, Bufo viridis and Bufo vittatus are also found, but are much less common.
