The transformation of ordinary physical objects into sacred tools reaches its peak through the act of anointing. This process goes far beyond a simple physical application of oil; it grants the objects a supreme spiritual status, turning them into sources of radiating holiness. The command to sanctify the objects is fulfilled entirely through the anointing oil [אבן עזרא, חזקוני]. There are no separate steps for anointing and sanctifying; the physical anointing is the very act that creates the holiness [מזרחי, גור אריה, שפתי חכמים]. This is not a mere technical procedure, but a profound elevation. It lifts the objects from their mundane state, dedicating them exclusively to the service of God and preparing them for their eternal purpose [רש"י, משכיל לדוד, ברכת אשר, אברבנאל]. Because of this profound change, the objects achieve the highest level of holiness in all matters related to the Tabernacle [חזקוני, העמק דבר].
This immense concentration of holiness has a direct impact on anything that comes into contact with the newly sanctified vessels. Commentators offer complementary perspectives on how this contact transfers holiness. From a legalistic standpoint, contact refers specifically to the placement of sacrifices and offerings into the service vessels [מלבי"ם]. A vessel can only sanctify an offering that is appropriate for its specific function, such as placing a dry offering in a vessel designed for dry materials, or pouring a liquid into a vessel meant for liquids. The moment an appropriate offering enters the vessel, it instantly absorbs this holiness. It is completely transformed, permanently stripped of its ordinary status, and can never again be treated as a mundane object [רש"י, תורה תמימה, רלב"ג, רש"ר הירש, ביאור יש"ר].
Other commentators broaden the meaning of this contact to include everyday objects and people. One perspective suggests that the holiness of the vessels is so intense that even completely ordinary items, such as bread, stew, or wine, will absorb some of that sacred energy simply by touching them. From the moment of contact, it becomes strictly forbidden to treat those everyday items as ordinary [אבן עזרא, קאסוטו, הכתב והקבלה, אדרת אליהו]. Another perspective shifts the focus to the people who approach the tools. Because of the extreme holiness radiating from these objects, anyone who wishes to touch them must first wash, purify, and prepare themselves. This acts as a strict warning that no one may touch the sacred vessels without a valid reason, with unwashed hands, or while in a state of impurity [רשב"ם, הדר זקנים, שטיינזלץ, חזקוני, אברבנאל].
