1 Chronicles 4:39

“And they went to the entrance of Gedor, etc.] There was a city of this name in the tribe of Judah, (<130418>1 Chronicles 4:18) but this seems to be further off, and perhaps is the same with Gedaris, mentioned by Strabo f35 along with Azotus and Askelon, cities that belonged to the Philistines; since it was inhabited by the posterity of Ham, of whom the Philistines were, as in the following verse: even unto the east side of the valley; which was near to Gedor, and a suitable place: to seek pasture for their flocks; their sheep and goats.”
