Akrabbim(Hebrew: scorpions) probably the general name given to the ridge containing the pass between the south of the Dead Sea and Zin, es-Sufah, by which there is an ascent to the level of the Negev desert. Scorpions are said to abound in this whole district, and hence the name (Num. 34:4). It is called "Maaleh-acrabbim" in Josh. 15:3, and "the ascent of Akrabbim" in Num. 34:4.
According to Num 34:4; Josh 15:3; Judg 1:36, Akrabbim was an outermost point on the southern borderline of the Judaean territory southwest of the Dead Sea....The ascent of Akrabbim should be connected with one of the passes between the Arabah and the Wadi Fiqre and Kurnub.
It proceeded to the south of the Ascent of Akrabbim, passed on to Zin, ascended to the south of Kadesh-barnea, passed on to Hezron, ascended to Addar, and made a turn to Karka.
And it lies in the "eastern" perimeter of the mountains bordering the Arabah, and it is to the south of the ascent of Akrabbim, commonly associated with Nagb es-Sfar (Safa, Sfai).
