The site consists of a series of rock-hewn burial chambers based on natural caverns. In 1979, two tiny silver scrolls, inscribed with portions of the well-known Priestly Blessing from the Book of Numbers and apparently once used as amulets, were found in one of the burial chambers. The delicate process of unrolling the scrolls while developing a method that would prevent them from disintegrating took three years. They contain what may be the oldest surviving texts from the Hebrew Bible, dating from the First Temple period around the late 7th to early 6th century BCE prior to the Babylonian Exile, and are now preserved at the Israel Museum.
