Skills of the KJB Translators Part 2: Lawerence Chaderton annonatated read and studied real Hebrew, read Hebrew rabbis' commentaries, and made annonatations to the Bombrrg Masoretic Text editions (see bottom of page 14 and page 15 from a 1700 book that talks about Lawrence Chaderton: "He made himself familiar with the Latin, Greek, and Hebrew tongues, and was thoroughly skilled in them. Moreover he had diligently investigated the numerous writings of the Rabbis, so far as they seemed to promise any aid to the understanding of the Scriptures. This is evident from the annotations in his handwriting appended to the Biblia Bombergi, * (*An edition of the Hebrew Bible, printed by Bomberg, at Venice, in 1518.) which are still preserved in the library of Emanuel College.' (*Vita Laurentii Chadertoni, a W. Dillingham, S. T. P. Cantab. 1700. Pp. 15, 24.)"
