Everyone agrees Tell ed-Duweir is Lachish. However, in the 1980s, Gota Ahlstrom rejected this identification in favor of Tell ‘Etun. Let us look at the evidence. Tell ‘Etun has no known 7th C BC remains. Neither does Tell Beit Mirsim (no stratum was detected between the Roman and Hezekian remains). Tell ed-Duweir does have Iron IIC remains (str. II). Ergo, since Lachish was the mightiest fortress in Judah besides Azekah, it makes perfect sense to postulate that it lay on the jutting wadi-carved ridge of Duweir. However, there are other criteria for Lachish. A double wall should be found on the site, and it should be a mighty fortress on a hill, as the Sennacherib relief shows. Also, it is to be expected it would have a similar culture as Azekah. This only fits Tell ed-Duweir and no other site in the Shephelah.
