I've been reading the Bible through. I figure that I ought to do this at least once. I'm reading from the ASV which I was told is the most literal of the English translations, but I have other translations close at hand. I also have a Criswell Study Bible (KJV). When reading I and II Samuel, I noted that Elhanan and David both killed Goliath. This appears to me to be a conflict. I read both passages in a KJV from Oxford Press. The KJV confirms the ASV. Then I read it in the Criswell text. Criswell (or his writers) inserts in the Elhanan account these words "the brother of Goliath". So I looked up how to read italics in this Bible. Criswell says we are allowed to use harmonization words to explain what the original writer/editor is really saying and to smooth over what appears to be conflicts within the Bible. So far; so good. The italics indicate an addition to the original text of the KJV. Then I consulted a KJV published by Baker Press. This version use the text as inserted as italics by Criswell. However, there are no italics here. The typeface is the same as all the words. This to me is unacceptable and deceitful. The inerrantists/fundamentalists have altered the received text.
All this raises another question. Does Rev 22:18 apply only to the book of Revelation or, at the last book in the Canon, does it apply to the whole Bible?
