Early secular scholars considered the Beta Israel to be the direct descendant of Jews who lived in ancient Ethiopia, whether they were the descendants of an Israelite tribe, or converted by Jews living in Yemen, or by the Jewish community in southern Egypt at Elephantine. In 1829, Marcus Louis wrote that the ancestors of the Beta Israel related to the Asmach, which were also called Sembritae ("foreigners"), an Egyptian regiment numbering 240,000 soldiers and mentioned by Greek geographers and historians. The Asmach emigrated or were exiled from Elephantine to Kush in the time of Psamtik I or Psamtik II and settled in Sennar and Abyssinia. It is possible that Shebna's party from Rabbinic accounts was part of the Asmach.
