mentioned by Yefet in the commentaries to I Sam. xx. 27; Dan. x. 3. Some fragments of this work were found in the Library of St. Petersburg and published by A. Harkavy. "'Iyyun Tefillah", in ten chapters, treating of all that pertains to prayer; extant in manuscript (Paris MS. No. 670). "Kalam", perhaps a liturgical work, extant in manuscript. Levi, Yefet's son, mentions in his "Muḳaddimah" to Deuteronomy another work by his father, entitled "Safah Berurah", the contents of which are unknown (the supposition of Fürst that it was a grammatical treatise is considered to be erroneous).
