You will notice that Job’s friends have three turns to speak. Here we listen to the first man again, Eliphaz. This was the man in chapter 4 who was basing his arguments on personal experience. What he had seen (Job 15:1717I will show thee, hear me; and that which I have seen I will declare; (Job 15:17)). Most people in the world today are doing exactly the same.
V.17-35 So here he is telling Job that God is not fooled. Wicked people suffer. He gives a long talk on all the things which happen to wicked people. He seems to be trying to convince Job that he is getting exactly what his life deserved!
