Geder

"A walled place, (Josh. 12:13), perhaps the same as Gederah or" Gedor (15:58).

"The fortress; a fortified place, a town in the plain (shephelah)" of Judah (Josh. 15:36). This is a very common Canaanite and Phoenician name. It is the feminine form of Geder (12:13); the plural form is Gederoth (15:41). This place has by some been "identified with Jedireh, a ruin 9 miles from Lydda, toward" "Eleutheropolis, and 4 miles north of Sur'ah (Zorah), in the" valley of Elah.

"An epithet applied to Josabad, one of David's warriors at Ziklag" "(1 Chr. 12:4), a native of Gederah."
