Shared ground
Job is still speaking to the same circle of friends. He calls them back into the discussion, but he does so with sharp dismissal: he does not expect to find real wisdom among them (v.10). The text presents Job as convinced that their counsel fails at the most basic level—accurately naming reality.
Job then explains why their words land as hollow. In his experience, the meaningful part of his life feels already behind him (“my days are past”), and what he had been aiming for has been cut off (“my plans are broken off”), including the inner “thoughts” or desires tied to those plans (v.11). This is not abstract philosophy for Job; it is his felt situation.
Finally, Job accuses “them” of reversing the situation by verbal relabeling—turning “night into day”—and insisting that “light is near” even while darkness is still present (v.12). Whatever hope they are offering, Job hears it as a false brightness spoken over unchanged darkness (see darkness).
Where interpretation differs (only where needed)
Two main questions are left open by the wording.
First, v.10 (“come on now again”) can be heard either as a literal invitation to continue the debate or as irony: “Sure, come back and say it again—it won’t help.” Both readings preserve Job’s verdict that their counsel lacks wisdom.
Second, v.12 (“they change the night into day”) raises the question of who “they” are. Most naturally it points back to the friends, since Job is addressing them and criticizing their speech. Some readers take it more broadly (people who talk like this in general), but the immediate setting still frames it as a critique of the friends’ approach.
Why the disagreement exists
The Hebrew allows a terse, punchy style, and pronouns can be flexible in poetry. Also, metaphors like “light” and “darkness” can point to external circumstances (safety, recovery, social standing) and to internal experience (despair, clarity, confusion). Those overlaps make multiple readings plausible without changing the overall direction of the passage.
What this passage clearly contributes
Explicitly, the text claims that Job rejects his friends’ wisdom (v.10), describes his life as effectively spent and his future as shattered (v.11), and accuses them of speaking “light” into a situation Job still experiences as “darkness” (v.12). By implication (but not as a stated doctrine), the passage highlights a moral danger in counsel that sounds hopeful yet misnames reality: it can function like calling night “day,” offering reassurance without addressing the darkness Job is actually facing (Job 17:10–12).
