beth-da'-gon (bethdaghon; Bethdagon):
⇒See a list of verses on BETH-DAGON in the Bible.
(1) A town in the Shephelah of Judah named with Gederoth, Naamah, and Makkedah (Jos 15:41). It may be represented by the modern Beit Dijan, about 6 miles Southeast of Jaffa. This however is a modern site, and not in the Shephelah. Nearly 2 miles to the south is Khirbet Dajan, a Roman site. The connection in which it occurs leads us to expect a position farther Southeast
(2) A city on the border of Asher (Jos 19:27) which Conder would identify with Tell D'auk, near the mouth of the Belus, in the plan of Acre.
⇒See also the McClintock and Strong Biblical Cyclopedia.
The name seems to have been of frequent occurrence. There is a Beit Dejan about 6 miles East of Nablus, and Josephus speaks of a fortress called Dagon above Jericho (Ant., XII, viii, 1; BJ, I, ii, 3). This would seem to indicate a widespread worship of Dagon. But the name may mean "house of corn."
