Fausset's Bible Dictionary [1]

A city in the S. border of Judah, next Edom ( Joshua 15:22). A Kenite settlement made directly after the fall of Jericho ( Judges 1:16). E. Wilton (Imperial Dictionary) would read for "Eder, and Jagur, and Kinah" "Arad and Hazor Kinah"; compare Septuagint, "Ara and Asor and Kinah." Some must be compound names, otherwise the list would exceed the number specified in  Joshua 15:32.

(Heb. Kinah', קַינָה , an Elegy, as in  Jeremiah 9:9, etc.; Septuag. Κινά v. r. Ι᾿Κάμ ), a city in the extreme south of Judah (hence prob. included within the territory of Simeon), mentioned between Jagur and Dimonah ( Joshua 15:22). " Stanley (Sinai And Pal. p. 160) ingeniously connects Kinah with the Kenites ( קְינַי ), who settled in this district ( Judges 1:16). But it should not be overlooked that the list in Joshua 15 purports to record the towns as they were at the conquest, while the settlement of the Kenites probably (though not certainly) did not take place till after it. It is mentioned in the Onomasticon of Eusebius and Jerome (s.v. Kiva, Cina), but not so as to imply that they had any actual knowledge of it. With the sole exception of Schwarz (Palest. p. 99), it appears to be unmentioned by any traveller, and the town Cinah, situated near the wilderness of Zin,' with which he would identify it, is not to be found in his own or any other map" (Smith). The true position of Kinah can only be conjecturallv located as not far from the Dead Sea, possibly in wady Fikreh.

International Standard Bible Encyclopedia [7]

kı̄´na ( קידה , ḳı̄nāh ): An unidentified town on the southern boundary of Judah, toward Edom (  Joshua 15:22 ). The word ḳı̄nāh means "elegy," "dirge," "lament for the dead." The name, however, may have been derived from the Kenites, קידי , who had settlements in the South ( 1 Samuel 27:10 , etc.).
