Gibeah

a hill or hill-town, "of Benjamin" (1Sam 13:15 ), better known as "Gibeah of Saul" (1Sam 11:4 ; Isa 10:29 ). It was here that the terrible outrage was committed on the Levite's concubine which led to the almost utter extirpation of the tribe of Benjamin (Judg 19:1 etc.; 20:1etc.), only six hundred men surviving after a succession of disastrous battles. This was the birthplace of Saul, and continued to be his residence after he became king (1Sam 10:26 ; 11:4; 15:34). It was reckoned among the ancient sanctuaries of Palestine (1Sam 10:26 ; 15:34; 23:19; 26:1; 2Sam 21:6 -10), and hence it is called "Gibeah of God" [(1Sam 10:5 ), R.V. marg.]. It has been identified with the modern Tell el-Ful (i.e., "hill of the bean"), about 3 miles north of Jerusalem.
