Shared ground
Job 20:10–11 is part of Zophar’s argument that a wrongdoer’s success does not last. The picture is of consequences that spread beyond the individual.
The text explicitly links the wrongdoer’s sin to (1) social and economic reversal affecting his household—especially his children—and (2) physical finality: even “youthful strength” ends in the dust of death. Wealth and vigor are treated as unable to secure a lasting future.
Where interpretation differs
Two main phrases are read in more than one responsible way.
First, “his children shall seek the favor of the poor” can be heard as the children pleading for acceptance and help from those once harmed, or as the children trying to appease them by making things right.
Second, “his hands shall give back his wealth” can be taken as repayment (restoration to victims) or as forced loss (wealth stripped away), though either way the point is reversal and loss rather than stable inheritance.
Why the disagreement exists
The Hebrew wording allows a range of social scenarios without spelling out the mechanics. The lines are poetic and compressed: they describe the outcome (humiliation, reversal, loss) more than the exact process (legal restitution, community pressure, or sheer collapse).
What this passage clearly contributes
These verses contribute a tight snapshot of moral fallout in Zophar’s worldview: exploitation does not stay private or confined to one generation. The aftermath reaches the next generation (“children”), reaches back toward the vulnerable (“the poor”), and reaches inward to the body (“bones…full of youth” yet ending “in the dust”). The passage states consequences; connecting those consequences to a universal rule about every case is an inference made in the larger debate of Job rather than a claim these two verses spell out on their own.
