Job"s friends had been selective in their observations regarding wicked people. They had pointed out only the cases in which God judged them on earth. Job now presented the other side of the story. There were many wicked who never experienced God"s judgment before they died. His words contrast especially with what Zophar had just said (ch20). Many people who do not know God or reject him live peaceful, pleasant lives ( Job 21:14-15; cf. Job 18:21). Job 21:16 may mean that these people"s prosperity comes ultimately from God, not from themselves. Still, Job did not want his friends to understand him as supporting the wicked"s contempt for God ( Job 21:16 b). [source][source][source]
