Iyov has said his piece. The three "friends" are out of words. Enter Elihu! A young man who has sat listening to each of the arguments. He is angry. He is besides himself. He cannot hold his words inside.
With great irony, in this chapter, Elihu just talks about talking, but in fact says very little.
