1 Samuel 23:26-30

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; for Saul and his men compassed David and his men round about to take them.

But there came a messenger unto Saul, saying, Haste thee, and come; for the Philistines have invaded the land.

Wherefore Saul returned from pursuing after David, and went against the Philistines: therefore they called that place Sela-hammahlekoth.

And David went up from thence, and dwelt in strong holds at En-gedi.
