The climax of a daily, agonizing struggle reaches a physical breaking point where words lose their power and immediate action is required. For a long period, Joseph faced severe threats of imprisonment, blindness, and death from his master's wife, yet he remained steadfast in his faith in God [דעת זקנים].
The confrontation escalates when she resorts to physical force. Knowing that merely speaking would cause him to run away instantly, she seizes his clothing tightly to trap him before she can even voice her demand [אדרת אליהו]. She assumes that this sudden physical contact and sheer boldness will overwhelm him with shame, making it impossible for him to refuse [אברבנאל]. Some suggest that no words were even necessary; the aggressive grasp of his clothing was in itself the ultimate demand [אור החיים].
A symbolic approach points to a deeper psychological argument regarding betrayal. She claims that because he had already entertained thoughts of the sin and compromised his values, he had lost his spiritual standing and therefore had no reason to hold back from the physical act. Alternatively, her grasp on his clothing serves as a hint that she is willing to adopt his faith and way of life, metaphorically putting on his garments, if only he will surrender to her [פני דוד, פרדס יוסף].
In response, Joseph makes a sudden sacrifice. The primary approach among commentators is that Joseph was physically stronger and could easily have yanked his clothing out of her hands. However, he chooses not to wrestle with her out of respect for her high status as his mistress [רמב״ן, רבנו בחיי, הטור הארוך, אברבנאל]. Practically, garments of that era were worn as loose cloaks or wraps, allowing him to slip out effortlessly [רמב״ן, ביאור שטיינזלץ]. He also fears that lingering even a moment to retrieve his clothing will give her another opportunity to grab him [אברבנאל]. Symbolically, he leaves the betrayal entirely in her hands, refusing to be pulled into the sin [פרדס יוסף].
His escape is understood not merely as a flight from her, but as a desperate retreat from his own internal desires. He rushes out of the closed room, terrified that his own burning inclination might overpower his resolve [ספורנו, צאינה וראינה, ביאור יש״ר]. At this critical juncture, the image of his father Jacob appears in his mind, reminding him of the profound spiritual consequences of his actions and granting him the final surge of strength needed to pull away [חומש קה״ת, שפתי כהן]. Stepping outside also serves to cool his physical intensity and sends her an unmistakable message that she has absolutely no chance of succeeding [רבנו בחיי].
His exit is calculated and precise. A panicked sprint through the city streets would immediately arouse suspicion and invite questions from bystanders. Therefore, he runs frantically only while within the walls of the house. The moment he crosses the threshold into the public street, he slows his pace, walking calmly and naturally to avoid drawing any unwanted attention [כלי יקר, ספורנו, העמק דבר, רש ר הירש].
This singular moment of immense bravery has lasting historical consequences. Because Joseph guards himself and flees from sin, his future descendants merit divine salvation. A traditional teaching connects his flight to the splitting of the Red Sea, explaining that the sea fled and split before Joseph's coffin as a direct, measure-for-measure response to the moment Joseph fled from transgression [כלי יקר, רבנו בחיי, דעת זקנים].
