I guess it’s all right, since Job just started a book about how unfair God is to him. We’re reading the KJV because that’s the version God used to speak directly to him. We don’t know why God used to speak directly to him (for the same reason the devil is here: because Job sinned in some way) – but if you’re in an argument with someone, sometimes it’s better to read the things they say they believe than to ask them what they meant.
That’s the first thing I had to pick out – I only read the first couple of pages and it was too short to tell what Job meant – but it doesn’t seem obviously wrong, and it’s something I’ve often wondered about.
