Positioning the Ark in the heart of the Tabernacle bridges heaven and earth, transforming the historic revelation at Mount Sinai into a permanent, living presence. The heavenly Tablets finally find a physical resting place on earth, serving as a lasting source of strength [ביאור שטיינזלץ]. The primary approach among commentators is that because the Tablets were not crafted alongside the rest of the Tabernacle's furnishings, they had been stored in a temporary wooden ark inside Moses's tent. Moses first had to retrieve them before he could place them into the golden Ark. While the Levites provided physical assistance in assembling other parts of the sanctuary, Moses performed the sacred task of placing the Tablets inside the Ark entirely with his own hands [העמק דבר].
The physical transfer of the Tablets carries deeper meaning. The act of taking them represents how the Torah serves as a profound lesson given to the Israelites [חומת אנך]. Furthermore, placing them inside is viewed as a gift to the Ark itself. On their own, the wood and gold held no inherent worthiness; they acquired their deep holiness strictly from the Torah placed within them [אלשיך]. These Tablets are known as the testimony [רש״י], as they bear witness to God resting His presence upon the Ark. This divine presence was demonstrated by a miracle where the Ark defied physical dimensions, occupying no actual space within the Holy of Holies [חומת אנך]. Inside, the Tablets did not stand upright like a modern scroll, but rather lay completely flat [פרדס יוסף].
Once the Tablets were resting inside, attention turned to the carrying poles. These poles had already been inserted into the rings by the craftsmen; Moses simply adjusted and arranged them so they protruded outward, ready for transport [העמק דבר]. Symbolically, these poles represent the individuals who provide financial support to those who study Torah. The placement of the poles upon the Ark suggests that the holiness of these supporters is even greater than that of the Ark itself, which serves merely as a vessel for the Torah [אלשיך]. Finally, the placement of the Ark's cover drew down the holiness of the Divine Presence from above, flowing from between the two cherubim [אלשיך].
There are differing perspectives on exactly how and when this cover was placed. One view suggests that Moses initially laid the cover sideways across the Ark as a temporary measure, making it easier to carry both pieces together into the Holy of Holies [העמק דבר]. Another perspective focuses on a shift in the order of events. Originally, the instructions required bringing the Ark inside the Holy of Holies first and only then placing the cover on top. However, Moses assembled them outside before bringing the complete unit inside. This change reflects a transition in time: the original instructions applied only to the seven days of the sanctuary's inauguration, whereas Moses's actions here established the permanent procedure that began on the eighth day [מלבי״ם].
