While most manuscripts of the Bible read six-hundred-sixty-six or 666 for the Number of the Beast in Revelation 13:18, some early manuscripts contain 616 instead. Codex Ephraemi Rescriptus (5th century) and Papyrus 115 (3rd or 4th century). Irenaeus knew about the reading 616, but according to Metzger, Bruce M. (1971) A Textual Commentary on the Greek New Testament, New York: United Bible Societies. ISBN 3-438-06010-8, p. 751, Irenaeus "says that 666 'is found in all good and ancient copies,' and is 'attested by those who had themselves seen John face to face.'" The minuscule manuscript 2344 (11th century) identifies the Number of the Beast as 665.
