"A fragment from the oldest surviving copy of the New Testament shows that the number of the Beast of Revelation 13 is 616. Ellen Aitken, a professor of early Christian history at McGill University, states that “the majority opinion seems to be that it refers to [the Roman emperor] Nero.”[1] The early fragment supports the view that Revelation was written prior to the destruction of Jerusalem in A.D. 70, and whether the number is 666 or 616, the number is a reference to Nero and not some end-time antichrist figure....."
"...The fragment supports the reading of some Greek New Testament manuscripts that read 616 instead of 666. Why would someone making a copy of the Revelation scroll make such a number change? “Perhaps the change was intentional, seeing that the Greek form Neron Caesar written in Hebrew characters (nrwn qsr) is equivalent to 666, whereas the Latin form Nero Caesar (nrw qsr) is equivalent to 616.” A Latin copyist might have thought that 666 was an error because Nero Caesar did not add up to 666 when transliterated into Latin. He then changed 666 to 616 to conform to the Latin rendering since it was generally accepted that Nero was the Beast. In either case, a Hebrew transliteration nets 666, while a Latin spelling nets 616. Nero was the “man” and either 666 or 616 was his number."
