Hidden under the simple description of “Old Testament (Orit)” lies a true treasure in the National Library of Israel in Jerusalem. Manuscript NLi Ms. Or. 87 is much more than a simple Orit manuscript. It contains as an additional text the second original piece of Betä Ǝsraʾel historiography ever to be discovered. So far only “A Falasha Religious Dispute” published by Wolf Leslau has been known to exist. As if this was not a significant discovery on its own, the document has even more to offer. This historiographical text is a monastic genealogy for Abba Wärqe, a monk of Hoharwa – the most important Betä Ǝsraʾel monastery, located on one of the seven holy mountains of this religious group.
