The Middle Turkic Biblical Ms. Evr. I Bibl. 143 from the first Firkowicz collection. Part II. The religious affiliation

The First Firkowicz Collection of the National Library of Russia in Saint Petersburg contains a Middle Turkic manuscript stored under accession number Evr. I Bibl. 143. It includes a translation of a large portion of the Torah written in the Hebrew script. In the present paper the author offers his own contribution to the question of whether this is a Rabbanite or Karaite work. This paper is a continuation of Németh (2025), in which it was argued that the language of this Biblical source is Middle Kipchak.
