A Key to the Peshitta Gospels (KPG) is a Syriac-English dictionary to the Syriac version of the Gospels. Two of the five volumes have been published (1991, 2000) in Bruce M. Metzger’s New Testament Tools and Studies series.
The second section of a lexical entry provides the corresponding Greek term(s) for every occurrence of that entry’s Syriac headword in the Peshitta Gospels.
The third section provides the references to every occurrence of the headword in Pusey and Gwilliam’s critical edition of the Syriac text of the Peshitta Gospels.
These features are used by the Institut für Neutestamentliche Textforschung, University of Münster, for the preparation of future editions of the Greek New Testament and has been adopted as the basis of a Syriac-English lexicon for all the Syriac versions of the New Testament.
