1 Samuel 23:19

(19) The Ziphites. — The words of these Ziphites, and the king’s grateful reply, show that they were very warm adherents of Saul, entirely devoted to his fortunes, and well aware of his passionate desire to be rid of David.

On the south of Jeshimon. — Jeshimon is not the name of a place, but it signifies a “desert” or “solitude” (see Isaiah 43:19). It is used here for the “dreary desert which extends between the Dead Sea and the Hebron Mountains.... It is a plateau of white chalk, terminated on the east by cliffs, which rise vertically from the Dead Sea shore to a height of above 3,000 feet. The scenery is barren and wild beyond all description.” — Conder: Tent Life in Palestine. This is the wilderness of Judea spoken of in Matthew 3:1. David was just then encamped with some of his followers in some thickets bordering on this trackless desert. The Ziphites evidently knew the country well, not only the hills, but the solitary wastes stretching out at its base. They were willing and ready, if Saul’s trained soldiers marched into their neighbourhood, to act as their guides in the pursuit or the famous outlaw and his men. They kept their promise faithfully, and in the pursuit which followed the arrival of Saul and his forces, David was in extreme danger of capture. The news that the Philistines had invaded the territories of Saul in great force hastily summoned the king from the district, and David was thus saved from a destruction which appeared to be imminent.
