Acrabbi terminus Iudaeae provinciae ad orientem respiciens, tribus Iudae. Est autem et vicus nunc usque grandis novem milibus a Neapoli contra orientem descendentibus ad Iordanem et Ierichum per eam quae appellatur Acrabbitene. Sed et confinium Amorraeorum Acrabbim dicitur, de quo loco non exterminavit alienigenas tribus Nefthalim, ut in Iudicum libro scriptum est.
(Jerome 15:7-12)

BIBLICAL BACKGROUND

Num 34:4-5 The (southern) Boundaries of Canaan
And your border shall turn from the south to the Ascent of Akrabbim, and pass on to Zin: and the going forth thereof shall be from the south to Kadesh-barnea, and shall go on to Hazar-addar, and pass on to Azmon: And the border shall fetch a compass from Azmon unto the river of Egypt, and the goings out of it shall be at the sea.

Judg. 1:34-36 The Ascent of Akrabbim (southern)
The Amorites pressed the Danites back into the hill country; they did not allow them to come down to the plain. The Amorites continued to live in Har-heres, in Aijalon, and in Shaalbim, but the hand of the house of Joseph rested heavily on them, and they became subject to forced labor. The border of the Amorites ran from the Ascent of Akrabbim, from Sela and upward.

1 Macc 5:3 Judas' War against the Idumeans
But Judas made war on the sons of Esau in Idumea, at Akrabattene, because they kept lying in wait for Israel. He dealt them a heavy blow and humbled them and despoiled them.
