Based on Isaiah 15:4-6. The cry of one town echoes to another, and is taken up afresh by its terrified inhabitants. Heshbon and Elealeh lay on eminences but a short distance apart, so that the shrill cry of lamentation would be heard far away in the southeast at Jahaz.
Zoar and Horonaim both lay in the southern half of Moah (see on Isaiah 15:3, Isaiah 15:4). An heifer of three years old. If this is the right rendering, the phrase is descriptive of Horonaim, which may, in the time of Jeremiah, have been a "virgin fortress."
But the phrase, thus understood, comes in very oddly, and in the parallel passage in Isaiah it stands, not after Horonaim, hut after Zoar; it hardly seems likely that there were two Gibraltars in Moab.
Another rendering (Ewald, Keil) is, "(to) the third Eglath." This involves an allusion to the fact that there were other places in Moab called Egiath or Eglah, which has been rendered highly probable by Gesenius.
The waters also of Nimrhn. Canon Tristram speaks of the "plenteous brooks gushing from the lofty hills into the Ghor-en-Numeira." Consul Wetzstein, however, says that nature appears there under so unspeakably gloomy an aspect, that the identification is impossible.
He proposes a site in the Wady So'eb, about fourteen miles east of the Jordan, which with its luxuriant meadows, covered with the flocks of the Bedouin, is probably suitable to the passages in Isaiah and Jeremiah.
So also Seetzen, who remarks that the lower part of this wady is still called Nahr Nimrin. In Joshua 13:27 a place called Beth—nimrah is mentioned as situated in the valley (i.e. the Jordan valley); no doubt this was in the wady referred to by the prophets.
"The valley" seems to have been sometimes used in a wider signification, so as to include lateral valleys like that of Nimrim. The antiquity of the name is shown by its occurrence in the Annals of Thothmos III; who penetrated into the heart of Palestine, and, in the temple of Karnak, enumerates the cities which he conquered.
From before B.C. 1600 to nearly A.D. 1900 this secluded valley has borne precisely the same name!
