Shem Tov's quotations of Matthew in "The Touchstone" are marked by Jewish thought, and are interspaced with the comments of the author. As a consequence several scholars feel it is difficult to determine which parts are Shem Tov's commentary, and which parts are the actual text of the source he was quoting. Many scholars view the text as a mediaeval translation from the Greek text of the Gospel of Matthew, as well as being the likely source of all later Hebrew versions of Matthew prior to the 20th century.
