(Heb. Netsib', נְצַיב, fixed, or a garrison [as in 1 Samuel 10:5; 1 Samuel 13:3-4; 1 Samuel 1 Clhron. 11:6]; Sept. Νασίβ, v. r. Νεσείβ ), a city in the Shephelah or maritime plain of Judah; mentioned between Ashnah and Keilah (Joshua 15:43), in the group in the south-western part of the hilly region (Keil, Comment. ad loc.). Eusebius and Jerome give it the same name (Νασίβ, Nazib), and place it at the ninth (Jerome, seventh) mile from Eleutheropolis towards Hebron (Onomast. s.v. Neesib). It is doubtless the present Beit- Nusib, situated on a rising ground, at the edge of the plain and mountain tract, two and a half hours from Beit-Jebrin towards Hebron (Robinson, Bib. Res. 2:343 sq., 404; 3:12; Schwarz, Palest. p. 104). It has ruins of considerable extent, especially a massive tower sixty feet square, with the foundations of another great fabric, and broken columns and large building-stones (Porter, Hand-book, p. 280). Tobler, however, describes it as "an insignificant cupola with a few ruins" (Dritte Wanderung, p. 150).
