You know that feeling when you're talking with 3 of your friends in poetic verse for a few days and then you find out there was another guy there the entire time? Job does.
This young guy, Elihu, apparently has been there this entire time and is pissed off at everybody. He goes on a rant and then disappears into the background again. Almost as if he was just an afterthought by the writer.
Then God finally addresses Job's complaints about killing his family, servants, and livestock by pointing out how much more powerful he is than Job. Thereby making killing everyone okay... I guess.
You know how powerful God is? Chapter 41 is dedicated to God making Godzilla (aka Leviathan). That's how powerful God is. So how could God do anything wrong?
Let's put this weird book to bed and move on with our lives!
