Albert Barnes Commentary 1 Samuel 23:14

"And David abode in the wilderness in the strongholds, and remained in the hill-country in the wilderness of Ziph. And Saul sought him every day, but God delivered him not into his hand." — 1 Samuel 23:14 (ASV)

Ziph is placed between Hebron and En-gedi (marginal references). (The wood of 1 Samuel 23:15 is taken by Conder as a proper name, “Cheresh,” and identified with Khoreisa.)
