How it was discovered
After the value of Cave 1 became clear, Bedouin searchers combed the marl terraces and limestone cliffs faster than the official teams. Cave 2 was located by Ta'amireh tribesmen in February 1952 and later surveyed by the joint École Biblique / Jordanian Department of Antiquities expedition.
Why it matters
Confirmed that the Qumran library extended beyond one cave and included apocryphal and wisdom literature alongside scripture.
