The coversation between God and Satan was that God was sending all these things at job. He was allowing satan to go as far as he could go. He was giving him all these trials. Basically God was testing Job and seeing how much he trust him. But as these trials kept going like his family getting killed him having the soars all over him. He starts to question God and doubting him. His friend is just going back and forth with him trying to tell him to quit doubting and to just trust him.
