The World of the Scrolls:
In 1947, Young Bedouin shepherds, searching for a stray goat in the Judean Desert, entered a long-untouched cave and found jars filled with ancient scrolls. That initial discovery by the Bedouins yielded seven scrolls and began a search that lasted nearly a decade and eventually produced thousands of scroll fragments from eleven caves. During those same years, archaeologists searching for a habitation close to the caves that might help identify the people who deposited the scrolls, excavated the Qumran ruin, a complex of structures located on a barren terrace between the cliffs where the caves are found and the Dead Sea. Within a fairly short time after their discovery, historical, paleographic, and linguistic evidence, as well as carbon-14 dating, established that the scrolls and the Qumran ruin dated from the third century B.C.E. to 68 C.E. They were indeed ancient! Coming from the late Second Temple Period, a time when Jesus of Nazareth lived, they are older than any other surviving biblical manuscripts by almost one thousand years.
