The ancient ruin is distinguished by its many razed structures lying in a field the size of a football field, interspersed with terebinths, directly alongside a small paved road that runs parallel to the main Roglit - Aderet road: see Survey of Western Palestine, 1878 Map, Map 21: IAA, Wikimedia commons, as surveyed and drawn under the direction of Lieut.

Claude R. Conder, in Tent Work in Palestine (pub.
Richard Bentley and Son: London 1878, p. 276 Archived 2017-08-25 at the Wayback Machine), wrote: "The term Shephelah is used in the Talmud to mean the low hills of soft limestone, which, as already explained, form a distinct district between the plain and the watershed mountains.
The name Sifla, or Shephelah, still exists in four or five places within the region round Beit Jibrîn, and we can therefore have no doubt as to the position of that district, in which Adullam is to be sought.
M. Clermont Ganneau was the fortunate explorer who first recovered the name, and I was delighted to find that Corporal Brophy had also collected it from half a dozen different people, without knowing that there was any special importance attaching to it.
The title being thus recovered, without any leading question having been asked, I set out to examine the site, the position of which agrees almost exactly with the distance given by Jerome, between Eleutheropolis and Adullam—ten Roman miles."

As for the word "east," this is not to be understood directly east in relation to Beit Gubrin (Eleutheropolis), as proven by other descriptions of biblical place names in Eusebius' writings, but can also mean "northeast", as in this case, or "southeast".
