Geba

the hill, (2Sam 5:25 ) [(1Chr 14:16), "Gibeon"]; (2Kings 23:8; Neh 11:31 ), a Levitical city of Benjamin [(1Kings 15:22; 1Sam 13:16 ; 14:5), wrongly "Gibeah" in the A.V.], on the north border of Judah near Gibeah (Isa 10:29; Josh 18:24; 18:28). "From Geba to Beersheba" expressed the whole extent of the kingdom of Judah, just as "from Dan to Beersheba" described the whole length of Palestine (2Kings 23:8). It has been identified with Gaba (Josh 18:24; Ezra 2:26 ; Neh 7:30 ), now Jeb'a, about 5 1/2 miles north of Jerusalem.
