2 Chronicles 29:3-9, 12-17

In the first month of the first year of his reign, Hezekiah, having first repaired the doors of The Temple of GOD, threw them open to the public. He assembled the priests and Levites in the court on the east side and said, “Levites, listen! Consecrate yourselves and consecrate The Temple of GOD—give this much-defiled place a good housecleaning. Our ancestors went wrong and lived badly before GOD—they discarded him, turned away from this house where we meet with GOD, and walked off. They boarded up the doors, turned out the lights, and canceled all the acts of worship of the GOD of Israel in the holy Temple. And because of that, GOD’s anger flared up and he turned those people into a public exhibit of disaster, a moral history lesson—look and read! This is why our ancestors were killed, and this is why our wives and sons and daughters were taken prisoner and made slaves.

The Levites stood at attention: Mahath son of Amasai and Joel son of Azariah from the Kohathites; Kish son of Abdi and Azariah son of Jehallelel from the Merarites; Joah son of Zimmah and Eden son of Joah from the Gershonites; Shimri and Jeiel sons of Elizaphan; Zechariah and Mattaniah sons of Asaph; Jehiel and Shimei of the family of Heman; Shemaiah and Uzziel of the family of Jeduthun. They presented themselves and their brothers, consecrated themselves, and set to work cleaning up The Temple of GOD as the king had directed—as GOD directed! The priests started from the inside and worked out; they emptied the place of the accumulation of defiling junk—pagan rubbish that had no business in that holy place—and the Levites hauled it off to the Kidron Valley. They began the Temple cleaning on the first day of the first month and by the eighth day they had worked their way out to the porch—eight days it took them to clean and consecrate The Temple itself, and in eight more days they had finished with the entire Temple complex.
