Sodot HaTefilah, J.T.S. Library, bound with and in same hand as preceding; ascribed to Naḥmanides, but really by Eleazar of Worms. "This commentary is an excellent illustration of the statement of R. Jeḥiel b. Asher (quoted in Tur Oraḥ Ḥayim, No. 113) that the ḥaside Ashkenaz had the custom to count the number of words in the prayers and to investigate why this number was chosen." (A. Marx, JQR, NS, II , 263.)
