 Early drawings depicting the so-called "Adullam cave" have tentatively been identified with the cavern of "Umm el Tuweimin", and the cave at "Khureitun" (named after Chariton the ascetic), because of their immense size.Modern-day archaeologists have rejected these early hypotheses.The Adullam Grove Nature Reserve is a nature reserve managed by the Israel Nature and National Parks Protection Authority.
