The moment the master of the house returns becomes a dramatic turning point, as his wife presents her carefully crafted version of events to arouse his jealousy and rage. She recounts the tale, either simply repeating the story she had already spread among the household staff [רמב״ן, שד״ל], or, according to the primary approach among commentators, timing her accusation for a moment of intimate closeness with her husband [רש״י]. This raises a physical question, as tradition notes the master had been made a eunuch upon purchasing Joseph for illicit purposes. To resolve how they could share such closeness, some explain that their intimacy consisted only of affectionate touch, such as embracing and kissing. During this time, she claimed Joseph had tried to force himself upon her in the exact manner they were currently sharing [רמב״ן, רבנו בחיי, הכתב והקבלה, גור אריה, דברי דוד]. Others suggest his physical desires were merely weakened rather than entirely removed, or that he remained capable of relations with a woman [דעת זקנים, פענח רזא, ברכת אשר, פרדס יוסף]. Alternatively, the timing of her accusation simply refers to the quiet hours of the night when couples typically converse in private [משכיל לדוד].
In delivering her accusation, the wife deliberately refers to Joseph as her husband's slave rather than her own. This calculated choice of words is designed to sting her husband for bringing the servant into their home, while emphasizing Joseph's profound disrespect in failing to view her as his mistress [ביאור יש״ר]. Furthermore, her framing attempts to create the false impression that Joseph had actually completed his malicious scheme [מלבי״ם], or at the very least, that his behavior had escalated from light mockery into a severe physical assault [העמק דבר].
The master reacts with intense anger, yet commentators unanimously agree on a crucial, subtle distinction: his rage is not directed at Joseph. The master knew Joseph to be a man of absolute integrity and deeply doubted, if not entirely disbelieved, his wife's fabricated tale. Had he truly believed a slave had assaulted his wife, he would have ordered an immediate execution, as was the standard punishment of the era. Instead, his fury is aimed squarely at his wife—for her deceitful accusations, her lies, and for bringing a Hebrew slave into the home only to cause a humiliating scandal [אבן עזרא, ספורנו, אברבנאל, מחוקקי יהודה, קונטרס חיבה יתירה, מלבי״ם].
Knowing Joseph was likely innocent, the master's decision to imprison him reveals a complex legal and social dilemma. His hands were tied. Because his wife had already publicized the scandalous story to the household staff and presented Joseph's abandoned garment as physical proof, the master was forced to act. He imprisoned Joseph to protect his wife's honor, prevent further public gossip, and quiet the uproar in his home. By settling for a prison sentence rather than execution, he managed to spare the life of an innocent man he favored, a sequence of events ultimately guided by a miracle from God [רמב״ן, ספורנו, פענח רזא, ביאור יש״ר, אברבנאל, קונטרס חיבה יתירה].
