The most inner and sacred part of Solomon's Temple, most commonly known as "Sanctum Santorum".
A Canaaniteking of Eglon, slain by Joshua. (Joshua chapter 10) Added by miracles, Joshua's army routed the Caananite military, forcing Debir and the other kings to seek refugee in a cave. There they were trapped until later executed.
A royal Canaanite city, also known as Kiriath-Sepher and Kiriath-Sannah. (Joshua 15:15) It became a Levite city. (Joshua 21:9) Its location is unclear, but today it is commonly identified with Khirbet Rabud southwest of Hebron.
A site mentioned to be in the low plain of Achor. (Joshua 15:7) Though its exact location is not known, the name may have survived in Thogheret ed-Debr, southwest of Jericho.
A location in Gilead, at the border of the Tribe of Gad, commonly believed to be the same as Lo-Debar. (Joshua 13:26) Some identfy the place with Umm ed-Dabar, 16 km (10 miles) south of Gennesareth Sea.
In Joshua 15:15-17 and Judges 1:11-13 is an account of how Othniel captured Debir, which "beforetime was Kiriath-sepher," and won thereby the hand of Achsah, Caleb's daughter.
(1) Debir is usually accepted as meaning "back," but this is doubtful; the word debhir is used to denote the "holy of holies" (1 Kings 6:5).
(2) Debir, on the border between Judah and Benjamin (Joshua 15:7), must have been somewhere East of Jerusalem not far from the modern Jericho road.
