Kirjath-sannah - See the note on Joshua 15:15.

And Dannah, and (k) Kirjathsannah, which [is] Debir,
(k) Which is also called Kirjath-sepher, (Joshua 15:15).

And Dannah,.... Dannah is not mentioned elsewhere:
and Kirjathsannah, which is Debir; Kirjathsannah had three names, this and Debir, and Kirjathsepher; See Gill on Joshua 15:15; all which are of much the same signification; for "Sanna" with the Arabs (f), and so with the Phoenicians, signifies law, doctrine, and manner of life; and with the Mahometans the secondary law to the Koran, and answers to the Jewish Misnah; and the Greek version interprets this name "the city of letters". Jerom (g) calls it Daenna, and seems to confound it with Dannah.

Dannah (Sept., Syr., Renna) is unknown. Knobel imagines that Dannah should be Danah, for Deanah, plur. Deanoth, which would then be suggestive of Zanute, the last inhabited place upon the mountains, five hours from Hebron, between Shuweikeh and Attir (see Rob. ii. p. 626; Seetzen, iii. p. 27, 29). Kirjath-sannah, or Debir, has not been traced (see at Joshua 10:38).
