1 Samuel 23:13-15

Then David and his men, about six hundred, arose and left Keilah, and they went wherever they could go. When Saul was told that David had escaped from Keilah, he gave up the pursuit. David stayed in the wilderness in strongholds, in the hill country of the Wilderness of Ziph. Saul searched for him every day, but God did not hand David over to him. Now David became aware that Saul had come out to seek his life. David was in the Wilderness of Ziph [in the woods] at Horesh.
