A wadi that extends southeast from Bethlehem toward the Dead Sea, about 11 miles south of Qumran.
The Bedouins discovered more Dead Sea Scrolls there in 1951, and in 1952, Harding and de Vaux excavated the caves there. They found biblical documents, letters, coins there from the time of the Second Jewish Revolt under Bar Kochba in A.D. 132-135. Documents include a Hebrew text of the Minor Prophets dating from the 2nd century A.D., fragments of the Pentateuch, and Isaiah.

The texts found at Wadi Murabba'at (copied during the 1st centuries A.D.) had very few variations from the standard Masoretic Text despite them being dated slightly later than the Dead Sea Scrolls. It seems the Hebrew consonantal text was already approaching a standard in Palestine by the first centuries A.D. Scholars have gone as far as to identify the Wadi Murabba'at texts as a proto-Masoretic standard.
