King Josiah initiates a sweeping physical and spiritual renewal within the Temple, turning his attention directly to the Levites. As the spiritual leaders who are holy and completely dedicated to serving the Creator, their primary role is to guide and teach the people [מצודת דוד, ביאור שטיינזלץ]. Josiah issues a profound directive regarding the Ark of the Covenant, marking a historic turning point in the nature of their sacred service.
The instruction concerning the Ark is understood in two distinct ways. A straightforward approach suggests that previous wicked kings, such as Manasseh and Amon, had removed the Ark from the Holy of Holies to make room for idols. Under this view, Josiah is simply instructing the Levites to restore the Ark to its rightful place [רש״י, מצודת דוד, מלבי״ם, ביאור שטיינזלץ]. However, some question this explanation, noting that Manasseh repented later in life and removed the idols, which raises the question of why he would not have returned the Ark himself [רד״ק].
Addressing this, the primary approach among commentators reveals a more dramatic scenario: Josiah actually commands that the Ark be permanently concealed. Aware of the impending destruction of the Temple and the future exile of the people—a realization reinforced by the prophecy of Huldah the prophetess—Josiah acts to prevent the Ark from falling into enemy hands. He orders it lowered into a deep, winding labyrinth of hidden vaults beneath the Holy of Holies, which King Solomon had constructed in advance for this exact purpose [רש״י, רד״ק, רלב״ג, מלבי״ם]. This perspective is supported by the fact that the Ark is notably absent from all historical records of vessels taken to Babylon or brought back to Jerusalem [רלב״ג]. Alongside the Ark, several other sacred items, including the jar of manna, Aaron's staff, and the anointing oil, are hidden away beneath a special stone [רד״ק].
Following the placement or concealment of the Ark, Josiah declares that the Levites no longer have a physical burden to carry on their shoulders. This signifies their permanent release from the historical duty they held since the days of wandering in the desert—transporting the Ark and the vessels of the Tabernacle [רלב״ג, מלבי״ם, מצודת דוד]. With this heavy task removed, the Levites can no longer use it as an excuse to avoid other responsibilities [רש״י]. Josiah urges them to dedicate all their newly freed time and energy to serving God and assisting the Israelites. Moving forward, their focus must shift entirely to other essential Temple duties, such as singing, managing the sacrifices, and helping the people slaughter and prepare their Passover offerings [רש״י, מצודת דוד, ביאור שטיינזלץ].
