It's one book, and it isn't even that long. You shouldn't need to study it. Also, if a book has a ton of contradictions, then it basically says nothing.

As a whole, it's a hateful book full of cruelty, misogyny, homophobia, and xenophobia. Or it's not. It just depends where you read. Therefore, it will justify your good will to other people, or your worst instincts. Both supported by the word of God.
