II Chronicles 29:12-19

Then these Levites arose: Mahath the son of Amasai and Joel the son of Azariah, of the sons of the Kohathites; of the sons of Merari, Kish the son of Abdi and Azariah the son of Jehallelel; of the Gershonites, Joah the son of Zimmah and Eden the son of Joah; of the sons of Elizaphan, Shimri and Jeiel; of the sons of Asaph, Zechariah and Mattaniah; of the sons of Heman, Jehiel and Shimei; and of the sons of Jeduthun, Shemaiah and Uzziel. And they gathered their brethren, sanctified themselves, and went according to the commandment of the king, at the words of the LORD, to cleanse the house of the LORD. Then the priests went into the inner part of the house of the LORD to cleanse it, and brought out all the debris that they found in the temple of the LORD to the court of the house of the LORD. And the Levites took it out and carried it to the Brook Kidron. Now they began to sanctify on the first day of the first month, and on the eighth day of the month they came to the vestibule of the LORD. So they sanctified the house of the LORD in eight days, and on the sixteenth day of the first month they finished. Then they went in to King Hezekiah and said, “We have cleansed all the house of the LORD, the altar of burnt offerings with all its articles, and the table of the showbread with all its articles. Moreover all the articles which King Ahaz in his reign had cast aside in his transgression we have prepared and sanctified; and there they are, before the altar of the LORD.”
