According to its preface, the NKJV uses the 1967/1977 Stuttgart edition of the Biblia Hebraica for the Old Testament, with frequent comparisons made to the Ben Hayyim edition of the Mikraot Gedolot published by Bomberg in 1524–25, which was used for the King James Version. Both the Old Testament text of the NKJV and that of the KJV come from the ben Chayyim text. However, the 1967/1977 Stuttgart edition of the Biblia Hebraica used by the NKJV uses an earlier manuscript (the Leningrad Manuscript B19a) than that of the KJV.
