The site of Adoraim is uncertain. For Lachish, see Joshua 10:3; Azekah, Joshua 10:10; Zorah, Joshua 15:33; Aijalon, Joshua 10:12; Hebron, Joshua 14:15. No one of the cities was really within the limits of the tribe of Benjamin. The writer uses the phrase "Judah and Benjamin" merely as the common designation of the southern kingdom (compare 2-Chronicles 11:12 and 2-Chronicles 11:23).

And Adoraim,.... Called by Josephus (d) Adora, which he mentions along with Mareshah, or Marissa:
and Lachish: a royal city in the time of the Canaanites, and which fell to the lot of Judah, Joshua 12:11,
and Azekah; a city situated in the plain of Judah, Joshua 10:10.
(d) Antiqu. l. 13. c. 9. sect. 1.

Adoraim (Ἂδωραΐ́μ in Joseph. Antt. viii. 10. 1), met with in 1 Macc. 13:20 as an Idumean city, Ἄδωρα, and so also frequently in Josephus, was taken by Hyrcanus, and rebuilt by Gabinius (Joshua. Antt. xiii. 15. 4, and xiv. 5. 3) under the name Δῶρα, and often spoken of along with Marissa (s. Reland, Palaest. p. 547). Robinson (Pal. sub voce) has identified it with the present Dra, a village about 7 1/2 miles to the westward of Hebron. Lachish, situated in the lowland of Judah, as we learn from Joshua 15:39, is probably the present Um Lakis, on the road from Gaza to Beit-Jibrin and Hebron, to the left hand, seven hours to the west of Beit-Jibrin, on a circular height covered with ancient walls and marble fragments, and overgrown with thistles and bushes; see on Joshua 10:3, and Pressel in Herz.'s Realenc. viii. S. 157f. Azekah, situated in the neighbourhood of Shoco (2-Chronicles 11:7), and, according to 1-Samuel 17:1, in an oblique direction near Ephes-dammim, i.e., Damm, one hour east to the south of Beit-Nettif,
(Note: Compare the interesting note of Breytenbach (Reybb. des heil. Landes, i. 134) in Tobler, dritte Wand. S. 463: "Thence (from Azekah) three miles is the city Zochot-Jude, not far from Nobah, where David slew Goliath.")
has not been re-discovered; see on Joshua 10:10.
