There are several KJV-only authors that have attempted to apply "purified seven times" to the KJV.
William Byers claimed that the KJV is the seventh translation in the English language from the pure text and is thus "purified seven times" (The History of the KJB, pp. 9, 23, 97-98). Byers wrote that the Geneva Bible was the "sixth translation" (p. 9), but later he wrote that "Geneva is five" (p. 97). .Although beginning his list with Wycliffe's Bible, Timothy Morton made a similar inaccurate claim to that of Byers when he wrote: "Each of these Bibles was (and still is) a valuable translation, but the King James of 1611 is the purest--the seventh and final purification" (Which Translation Should You Trust, p. 9). Doug Stauffer maintained that "the King James Bible became the seventh purification of the English translation in fulfillment of this prophecy" [Ps. 12:6] (One Book Stands, p. 282).
William Bradley stated: "The King James Bible was the seventh major English translation of the Scriptures" (To All Generations, p. 29). Bradley also began his list with Wycliffe's Bible and included Tyndale's, Coverdale's, Matthew's, Great, and Geneva Bibles, but he omitted the important Bishops' Bible of which the KJV was officially a revision. In his later book, Bradley actually listed a total of eight English translations in two consecutive paragraphs [Wycliffe's, Tyndale's, Coverdale's, Matthew's, Great, Geneva, Bishops', KJV], which actually made the KJV the eighth translation (Purified, p. 116). Nevertheless, Bradley claimed: "When the seventh major English translation of the Bible was published, the Word of God in English was complete; it was perfect" (Ibid., p. 131). Ed DeVries also asserted that the KJV is "the seventh major translation of the Bible in the English language" (Divinely Inspired, p. 28). In his list, DeVries listed Wycliffe's, Tyndale's, Matthew's, Great, Geneva, Bishops', and KJV, but he omitted the important 1535 Coverdale's Bible. Phil Stringer also proposed: “It took several decades and seven major translations (Tyndale, Coverdale, Matthew’s, Great Bible, Bishops, Geneva, King James) in order to get the pure Word of God in English” (Carter, Elephant, p. 47). Joey Faust listed the KJV as the seventh English translation, and he asserted: “The Authorized Version (i. e. KJV) is the final purification” (The Word, p. 45). T. S. Luchon also used this argument, listing the KJV as the claimed seventh English Bible (From the Mind of God, p. 66).
Gail Riplinger also adopted a variation of this same KJV-only argument. Riplinger contended that “the English Bible was ’purified seven times’ and that “the KJV is its seventh and final purification” (In Awe, p. 131). In her book, Riplinger maintained that “the English Bible’s seven purifications are covered, including, the Gothic, the Anglo-Saxon, the pre-Wycliffe, the Wycliffe, the Tyndale/Coverdale/Great/Geneva, the Bishops, and the King James Bible (p. 33) [see also pp. 131, 843, 852]. She proposed that “the KJV was the seventh polishing of the English Bible” (p. 137). This seems to be one of the main themes of her KJV-only book. Would it be acceptable KJV-only math and reasoning for four translations to be counted as one?
