Judges 1:36

The going up to Akrabbim -See the margin and references; properly “the ascent of scorpions,” with which the whole region abounds. The rock -Petra, the capital of Idumea, so called from the mass of precipitous rock which encloses the town, and out of which many of its buildings are excavated. The original word “Selah” is always used of the rock at Kadesh-BarneaNumbers 20:8-11, near Petra (compareObadiah 1:3). This leads us to look for “the ascent of scorpions,” here coupled withסלעהסhas-sela‛, in the same neighborhood.
