The Textual Basis of the KJV
wNT ultimately based on the edition of the Greek NT by Erasmus in 1516.
wErasmusŐ edition was based on only a few manuscripts; the oldest (10th cen) was least used.
wErasmus had only one (incomplete) manuscript of Revelation; he supplied the last 6 verses from Latin.
wActs 9:6 and 1 John 5:7-8 were also supplied from the Latin.
