Job 15:29
He shall not be rich, neither shall his substance continue, neither shall he prolong the perfection thereof upon the earth. He shall not be rich, neither shall his substance continue, neither shall he prolong the perfection thereof upon the earth.
This declaration comes in Eliphaz's second speech bringing fresh accusations against Job, answered by Job protesting his innocence and desiring death. It stands within the extended debate between Job and his three friends in chapters 3-31 over the cause and object of human suffering. In it Eliphaz argues from human wisdom and observation that the riches and substance of the wicked will not last, continue, or be prolonged on the earth.
The underlying principle that evil is ultimately punished is generally true, but Eliphaz misapplied it to Job. Affliction and suffering do not prove that the sufferer is under the displeasure of God. The statement belongs to Eliphaz's mistaken claims about Job and is not reliable truth about God's dealings. It must therefore be tested against other inspired declarations rather than treated as a sound rule that God's favor is shown by worldly prosperity.
