Here is an explanation of Jack Hyles' changing views on the King James Version, from a Hyles-supportive web site - the author admits that Hyles "corrected" the KJV text prior to 1984:

In this article, Josh Teis discusses the change of Hyles from non-KJV only to KJV only:
"Jack Hyles,
a close friend and associate of Rice for over twenty-two years, also valued other versions of the Bible, at least until the 1980s. In Hyles’ commentary on Revelations [sic]
he repeatedly corrects the King James Version and the TR, such as in his note on Revelation 8:13, which reads 'an angel flying' in the KJV. Hyles argued that 'The word "angel" here should be "eagle"' following the Critical Text and the RV."
Here is the full text of Hyles' commentary on Revelation. At 6:1 he proposes that this verse should read simply "Come" instead of "Come and see."

I have no connection to HAC. I was baptized at FBC-Hammond in October, 1988 but never attended again - I heard Hyles preach at various churches in the Chicago area and in 1984 at Miller Road Baptist in Garland, Texas (now defunct, his son Dave Hyles destroyed that church).
