Geder
The name Geder means “Gederah, Gederoth, a wall”.
Easton's Bible Dictionary 1897
A walled place, (Josh. 12:13), perhaps the same as Gederah or Gedor (15:58).
Smith's Bible Dictionary 1863
(a wall). The king of Geder was one of the thirty-one kings who were overcome by Joshua on the west of the Jordan. (Joshua 12:13) (B.C. 1445.) It is possible that it may be the same place as the Geder named in (1 Chronicles 4:39)
