Easton's Bible Dictionary Waters of yellowness, or clear waters, a river in the tribe of Dan (Joshua 19:46). It has been identified with the river `Aujeh, which rises at Antipatris. Int. Standard Bible Encyclopedia ME-JARKON me-jar'-kon (me ha-yarqon; thalassa Hierakon): The Hebrew may mean "yellow water." The phrase is literally, "the waters of Jarkon." Septuagint reads "and from the river, Jarkon and the boundary near Joppa." From this possibly we should infer a place called Jarkon in the lot of Dan; but no name resembling this has been found.
