Eliphaz assumes that Job’s wealth must have been acquired through wickedness (otherwise, Job would not have lost his wealth). In Job 22:6–9 Eliphaz describes the specific sins that Job must have committed for God to punish him so.
First, Eliphaz accuses Job of exploiting his debtors. It was an acceptable practice to take a debtor’s cloak and give it back once the debt has been repaid. The cloak served as security.
However, God’s law forbade the keeping of a poor man’s cloak after nightfall (Deuteronomy 24:10–13). According to Eliphaz, the wealthy Job had stripped
his debtors of their clothing.
6 For you have exacted pledges of your brothers for nothing and stripped the naked of their clothing.
