Job 32:2-3, 5

Then Elihu son of Barakel the Buzite, of the clan of Ram, became angry. He was angry because Job refused to admit that he had sinned and that God was right in punishing him. He was also angry with Job’s three friends, for they made God appear to be wrong by their inability to answer Job’s arguments.

But when he saw that they had no further reply, he spoke out angrily.
