Has anyone noticed when reading the New World Translation, that there are numerous dashes where scriptures are supposed to be? You look through, find the number, but instead of the text there is a dash. And, when you question it, all they say is that the King James version had a "spurious" scripture there.
The real reason was that, wherever a scripture that blatantly undermined the Watchtower Society appears, they deleted it. However, they had to keep the numbers consistent or they would lose others who are using the King James version. Thus, they would put the dash following the number. Usually, when I read the missing text, it fits in with the context of what's being said. That is, it belongs in the Bible. If only whoever was writing that up and then passing that on as the accurate translation would have read Revelation 22:18 and 19 where it warned what would happen to anyone who tampered with the Bible.
Mistake? Had they merely omitted the whole thing, then it might have been an error. But to put the number followed by the dash indicates that they are knowingly omitting something that belongs in the Bible. And there are literally hundreds of these dashes scattered through the New World Translation. And they are passing this on as inspired?
