se-la-ha-ma'-le-koth, -koth (cela`ha-machleqoth; petra he meristheisa): "The rock of divisions (or, escape)" (1 Samuel 23:28 margin). "Saul.... pursued after David in the wilderness of Maon. And Saul went on this side of the mountain, and David and his men on that side of the mountain: and David made haste to get away for fear of Saul" (1 Samuel 23:25, 26). The name seems to survive in Wady Malaki, "the great gorge which breaks down between Carmel and Maon eastward, with vertical cliffs" (PEF, III, 314, Sh. XXI).
