 Gederah
    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.
