This place name appears in Joshua 15:43 in the list of towns allotted to the tribe of Judah, specifically in the Shephelah (lowland) region near Philistine territory. The Septuagint preserves variations like Naseib and Neseib. Modern identification places it at Beit Nasib, approximately eight miles northwest of Hebron. The location on Judah's western frontier made it strategically significant as a buffer against Philistine expansion. The name itself may derive from a root meaning 'to stand' or 'to be set,' possibly referring to its position or a standing pillar.
