ויקרא, פרק י״ג, פסוק נ״ג

At the conclusion of a suspected infected object's first week of quarantine, a critical re-examination takes place to determine its fate. The priest conducts this inspection exactly at the end of the initial seven-day isolation [ביאור שטיינזלץ]. Often, the evaluation reveals a middle ground where the suspicious mark remains entirely unchanged in its dimensions. Commentators refer to this static condition as standing, meaning the affliction has not spread. At this specific stage of the process, the evaluation focuses exclusively on the physical size of the mark. Any potential changes in the color or shade of the spot are not considered yet, as those details are addressed later in the diagnostic process [תורה תמימה, רש ר הירש, אדרת אליהו].

Because the mark did not expand during the first week, the object is spared from immediate destruction and burning. However, it cannot be declared pure either. Instead, it requires a second period of quarantine. Before the item is isolated again, the affected area must undergo a specific treatment [רלב״ג, רש ר הירש, רד צ הופמן]. Commentators agree that the washing required at this point is not a ritual immersion meant for spiritual purification. Rather, it is a thorough, physical scrubbing of the spot itself using strong cleaning agents. This intense cleaning serves as a practical test. If the mark is merely surface dirt, the scrubbing will wash it away. But if the affliction is fundamentally embedded deep within the fibers or the leather, it will remain visible despite the washing [רלב״ג, ביאור יש״ר, רד צ הופמן].

This physical cleaning requirement is universally applied. The detailed listing of various materials, such as woven garments, warp and woof threads, and leather items, is intentional. It teaches that the practical test of scrubbing the stain must be performed on every single type of suspected article without exception, ensuring that even leather goods undergo the exact same diagnostic treatment [העמק דבר].
