1-20-2013: Dr. William Rutherford of HBU identified these as Coptic. He thought it probably was Bohariric Coptic, a later Coptic dialect, since the notes on the margin of one sheet are in Arabic. From the red inscription on one leaf, it looks like it comes from Luke 1:38-41. Another sheet identifies it as a psalm that mentions virgins, but couldn't pin down which psalm it might be. It's not necessarily an OT psalm.
Peter Williams, of Tyndale House, Cambridge on 9/19/2016, viewed the manuscript. He said this is not a Psalm, but is a coptic manuscript of Luke 1. The words Zacharias, Greeting, Mary, and Elizabeth can be easily determined. This probably dates from around the 8th century. There are some Arabic markings as well, dating it after the 6th century.
