|Easton's Bible Dictionary|
A cave, a place in the northern boundary of Palestine (Joshua 13:4). This may be the cave of Jezzin in Lebanon, 10 miles east of Sidon, on the Damascus road; or probably, as others think, Mogheirizeh, north-east of Sidon.
Int. Standard Bible Encyclopedia
me-a'-ra (me`arah; omitted in the Septuagint): A town or district mentioned only in Joshua 13:4, as belonging to the Zidonians. The name as it stands means "cave." If that is correct it may be represented by the modern village Mogheiriyeh, "little cave," not far from Sidon. Perhaps, however, we should find in the word the name of a Sidonian city, with the preposition min, that has suffered change in transcription. Septuagint reads "from Gaza"; but Gaza is obviously too far to the South.
