modern Nahr Zerka, i.e., the "crocodile brook," or "blue river",
which rises in the Carmel range and enters the Mediterranean a
little to the north of Caesarea (Josh. 19:26). Crocodiles are
still found in the Zerka. Thomson suspects "that long ages ago
some Egyptians, accustomed to worship this ugly creature,
settled here (viz., at Caesarea), and brought their gods with
them. Once here they would not easily be exterminated" (The Land
and the Book).
