The KJV was revised 4 times. We used 1769 KJV today. Therefore the 1611 KJV and the 1769 KJV are the SAME title – KJV. No new translation until NKJV was appeared. However modern versions are not revised because they are different versions, i.e. NIV and NIRV. Why not revised? For example, The KINGDOM of the CULTS by Walter Martin was revised 3 times, but it is SAME title of this book. When the NIV was not satisfied, then NIRV is next new version. When the ASV was not satisfied, then NASB is next new version. When the NIV was not satisfied, then TNIV is next new version. When the KJV was not satisfied, then NKJV is next new version. See the difference between a revision and a new version. Why is a new version necessary after an old version? Who needs a new version after not satisfied with an old version?
