Shared ground
Elihu presents affliction as a situation that can feel like being tied up and trapped ("fetters" and "cords"). In that setting, he says God brings moral clarity: God "shows" people their deeds and their wrongs, with special attention to proud or defiant behavior (explicit in v. 9). The picture then moves from exposure to instruction: God makes them able to hear teaching and calls for a real change of direction away from wrongdoing (v. 10).
Elihu frames the outcome as conditional, using repeated “if” language (vv. 8, 11, 12). Listening/obeying and serving leads to “prosperity” and “pleasures,” while refusal ends in ruin and death “without knowledge” (vv. 11–12). These are the text’s main stated claims.
Where interpretation differs
Who “they” are. Some read “they” mainly as basically upright people who still need correction (since the surrounding context mentions God’s care for the upright). Others read “they” more generally as anyone in trouble, including wrongdoers, because the verses speak directly about “transgressions” and a call to turn from “iniquity.”
How literal the promised outcomes are. Some take “prosperity” and “pleasures” as fairly straightforward life outcomes (security, well-being, flourishing). Others hear them as wisdom-style shorthand for the good life under God’s guidance, without guaranteeing that every listener will experience immediate material success.
What “die without knowledge” means. Some think it means dying in ignorance—never accepting the instruction available in suffering. Others think it points to dying in folly, without true insight or readiness, emphasizing the moral dimension more than lack of information.
Why the disagreement exists
The passage is poetry inside an ongoing argument about how God relates to sufferers. Elihu speaks in general patterns (“if…then…”) rather than narrating one person’s full story, so readers must decide how tightly it applies to Job’s specific case. Key phrases (“their work,” “prosperity,” “without knowledge”) are brief and can be heard either concretely or as wisdom-language summarizing typical outcomes.
What this passage clearly contributes
Elihu adds a category beyond “suffering as payback”: suffering can function as confrontation and instruction, especially exposing pride (vv. 8–10). He also insists that response matters: the text explicitly links listening/serving with life going well, and refusing to listen with destruction and a death marked by lack of insight (vv. 11–12). This frames affliction as a decisive moment that can either deepen wisdom or end in hardened refusal.
