What Does Genesis 42:12 Mean?

He said to them, "No, it is the nakedness of the land that you have come to see." Joseph's repetition of the accusation after their denial maintains the official pressure. He is not persuaded by their protest; he reasserts the charge. The persistence of the accusation against their denial mirrors the structure of a formal interrogation: the accused denies; the authority repeats the charge; the accused must provide more evidence of innocence. By refusing to accept their first denial, Joseph forces them to give more information: which will produce the family information he needs in verse 13.

The specific repeated charge: "the nakedness of the land that you have come to see": is the charge that a famine-weakened country is especially vulnerable to. A land in the middle of a severe seven-year famine, with its population depleted and its agricultural productivity at zero, is precisely the kind of land that a military power might want to assess for invasion. The charge is not arbitrary; it is contextually plausible within the famine narrative. Egypt has what the world needs; Egypt in its famine-feeding role is also a target. The administrative paranoia about foreign observers is legitimate from an Egyptian security perspective.

From the reader's perspective, the repeated charge is the mechanism of the test. Joseph needs his brothers to talk. He needs to hear about his father, about Benjamin, about the family situation. A quick procedural grain sale would give him nothing. The spy accusation and its sustained maintenance forces a conversation that will eventually produce all the information Joseph is seeking: and will eventually produce the demand that Benjamin be brought to Egypt, which is the next stage of the test. The "no" of verse 12 is not a fixed belief but a sustained interrogation strategy.
