Job 21:19 → Deuteronomy 5:9

Deuteronomy 5:9 declares that God visits the עָוֹן (avon, "iniquity") of fathers upon children to the third and fourth generation of those who hate Him—a principle embedded in the Decalogue itself. Job 21:19 directly challenges the application of this doctrine, arguing that God should repay the wicked man himself rather than storing up punishment for his children: "Let God repay the man himself, so he will know it." Job's protest does not deny the Deuteronomic principle outright but exposes the injustice of a simplistic application where the sinner prospers while his descendants bear the consequences. This tension between corporate solidarity and individual accountability becomes a major thread in Israel's theological reflection, taken up explicitly by Ezekiel 18. Job's engagement with the Decalogue formula demonstrates that wisdom literature served as a critical testing ground for Torah theology. The Deuteronomic clause itself reads פֹּקֵד עֲוֺן אָבוֹת עַל בָּנִים (poqed 'avon 'avot 'al banim, "visiting the iniquity of fathers upon children"), the very generational principle Job's protest presses against its own logic.
