I am wondering this too. Is the KJV the best bible to read that's most closely tied to the original text? I read the NLT and I don't know if it omits some of the verses.
LOL Welcome to the great debate

All versions claim they're closest to the original. All have flaws, some more than others. I use the KJV because I grew up with it, but you're going to need a dictionary for some words. As I said above, I like
http://www.theword.net because it has the originals and dictionaries so when a debate comes about I can see for myself what the originals said. There's a lot to be said to learning the written Hebrew too as there are some really cool things; literally a broken letter written, larger and smaller letters and since "fonts" is a modern invention, rather cool to find in the original Hebrew. In the Greek, where it's translated six hundred threescore and six, you'll find three Greek letters that do not mean anything so the assumption is they represent numbers since Greeks, like Hebrew, doesn't have numerical numbers, but use their alphabet to express numbers; however, Revelation 13:18 is the first, which begs the question, why. Every numerical reference is spelled out; like
שִּׁשִּֽׁי (sixth) instead of (6)
ו.
Revelation is the only book that commands not to change the words and when you see the oldest handwritten version you'll see those three letters resemble something else. Maybe John wrote something instead of a word and as his book was copied they assumed they were Greek letters seeing how the rest of the book was written in Greek. Either way, it's a first usage like this throughout the scriptures. Needless to say, there is a lot lost in translation.
