2 Chronicles 29:14-19

and of the sons of Heman, Jehuel and Shimei; and of the sons of Jeduthun, Shemaiah and Uzziel. They gathered their brothers and consecrated themselves and went in as the king had commanded, by the words of the LORD, to cleanse the house of the LORD. The priests went into the inner part of the house of the LORD to cleanse it, and they brought out all the uncleanness that they found in the temple of the LORD into the court of the house of the LORD. And the Levites took it and carried it out to the brook Kidron. They began to consecrate on the first day of the first month, and on the eighth day of the month they came to the vestibule of the LORD. Then for eight days they consecrated the house of the LORD, and on the sixteenth day of the first month they finished. Then they went in to Hezekiah the king and said, “We have cleansed all the house of the LORD, the altar of burnt offering and all its utensils, and the table for the showbread and all its utensils. All the utensils that King Ahaz discarded in his reign when he was faithless, we have made ready and consecrated, and behold, they are before the altar of the LORD.”
