Joshua 15:15 - Albert Barnes' Notes on the Bible

The name Debir belonged to two other places; namely,, that named in Joshua 15:7, between Jerusalem and Jericho, and the Gadite town mentioned in Joshua 13:26. The Debir here meant appears (and its site has been conjecturally placed at Dhaheriyeh (Conder)) to have been situated in the mountain district south of Hebron. It was one of the towns afterward assigned to the Levites. Its other name Joshua 15:49, “Kirjath-sannah”, i. e. perhaps, “city of palm branches,” or “city of law, or sacred learning,” no less than the two given in the text, would indicate that Debir was an ancient seat of Canaanite learning, for Debir probably is equivalent to “oracle,” and Kirjath-sepher means “city of books.” This plurality of names marks the importance of the town, as the inducement held out in Joshua 15:16, by Caleb, to secure its capture (compare 1 Samuel 17:25; 1 Samuel 18:17), points to its strength.
