Shared ground
Elihu points Job to the sky as a visual way to grasp the gap between God and humans: “the skies… are higher than you.” On that basis he asks two matched questions. First, even if a person sins and keeps adding wrong on top of wrong, what real effect does that have “against him” (God)? Second, even if a person is righteous, what can that person give God, as though God “receives” something from a human hand?
A shared takeaway is that Elihu is stressing God’s independence. God is not pictured as a needy being who can be enriched by human goodness or diminished by human wrongdoing. The language of “receive from your hand” makes the point with transaction imagery: humans are not supplying something God lacks.
Where interpretation differs
Some read Elihu’s “against him” language as meaning sin does not touch God at all—only humans are affected. Others read it as meaning sin is truly “against” God morally, but it does not give the sinner leverage over God or reduce God’s greatness.
Some also hear the “look to the heavens” image mainly as distance (God is far removed). Others hear both distance and authority (God is above in rank), without implying God is absent.
Why the disagreement exists
The passage uses rhetorical questions rather than direct explanations, and the sky image can suggest more than one idea at once. Also, “receive from your hand” could be heard broadly (any human action) or more narrowly (offerings), and that affects how readers frame Elihu’s point.
What this passage clearly contributes
Explicitly, Elihu argues that human sin and human righteousness do not add to or subtract from God as if God were dependent on human input (vv. 6–7). Theological inference: this supports a view of God as self-sufficient and not manipulable by human behavior, even while the wider book still treats human actions as meaningful and morally serious (the next verse shifts attention to human-to-human effects; Job 35:8).
