This unusual design is an imitation of the lid of a scroll jar. The museum holds the scrolls that were found in Qumran. They became known as the
dead sea scrolls. Written in the first century by "the sons of light", copies were found from almost every Old Testament book (except Esther, which has not definitively been found, yet). Because of these early copies, we know that our current translations have been copied with care throughout the centuries. Scribes were very conscientious when copying the books of the Bible.
This black granite wall is a contrast with the white dome - a reference to the battle between the children of darkness and the children of light, described in the scroll known as the
war scroll.
