Jamieson, Fausset and Brown on 1 Samuel 23:25

25. David ... came down into a rock, and abode in the wilderness of Maon--Tell Main, the hillock on which was situated the ancient Maon (Jos 15:55), and from which the adjoining wilderness took its name, is one mile north, ten east from Carmel. The mountain plateau seems here to end. It is true the summit ridge of the southern hills runs out a long way further towards the southwest; but towards the southeast the ground sinks more and more down to a tableland of a lower level, which is called "the plain to the right hand [that is, to the south] of the wilderness" [Van De Velde].
