1 Samuel 23:13-15

So David and his men got out of there. There were about six hundred of them. They left Keilah and kept moving, going here, there, wherever—always on the move. When Saul was told that David had escaped from Keilah, he called off the raid. David continued to live in desert hideouts and the backcountry wilderness hills of Ziph. Saul was out looking for him day after day, but God never turned David over to him. David kept out of the way in the wilderness of Ziph, secluded at Horesh, since it was plain that Saul was determined to hunt him down.
