1. David . . . escaped to the cave Adullam—supposed to be that now called Deir-Dubban, a number of pits or underground vaults, some nearly square, and all about fifteen or twenty feet deep, with perpendicular sides, in the soft limestone or chalky rocks. They are on the borders of the Philistine plain at the base of the Judea mountains, six miles southwest from Beth-lehem, and well adapted for concealing a number of refugees.

     1, 2. the Ziphites came unto Saul to Gibeah—This people seem to have thought it impossible for David to escape, and therefore recommended themselves to Saul, by giving him secret information (see on 1Sa 23:19). The knowledge of their treachery makes it appear strange that David should return to his former haunt in their neighborhood; but, perhaps he did it to be near Abigail's possessions, and under the impression that Saul had become mollified. But the king had relapsed into his old enmity. Though Gibeah, as its name imports, stood on an elevated position, and the desert of Ziph, which was in the hilly region of Judea, may have been higher than Gibeah, it was still necessary to descend in leaving the latter place; thence Saul (1Sa 26:2) "went down to the wilderness of Ziph."
