2 Chronicles 29:3-19

³In the first year of his reign, in the first month, he opened the doors of the house of the LORD, and repaired them. ⁴He brought in the priests and the Levites, and assembled them in the square on the east, ⁵and said to them, "Hear me, Levites! Now sanctify yourselves, and sanctify the house of the LORD, the God of your fathers, and carry out the filth from the holy place. ⁶For our fathers have been unfaithful and have done what was evil in the sight of the LORD our God; they have forsaken him, and have turned away their faces from the habitation of the LORD, and turned their backs. ⁷They also shut the doors of the vestibule and put out the lamps, and have not burned incense or offered burnt offerings in the holy place to the God of Israel. ⁸Therefore the wrath of the LORD came on Judah and Jerusalem, and he has made them an object of horror, of astonishment, and of hissing, as you see with your own eyes. ⁹For lo, our fathers have fallen by the sword and our sons and our daughters and our wives are in captivity for this. ¹⁰Now it is in my heart to make a covenant with the LORD, the God of Israel, that his fierce anger may turn away from us. ¹¹My sons, do not now be negligent, for the LORD has chosen you to stand in his presence, to minister to him, and to be his ministers and burn incense to him."

¹²Then the Levites arose, Mahath the son of Ama'sai, and Jo'el the son of Azari'ah, of the sons of the Ko'hathites; and of the sons of Merar'i, Kish the son of Abdi, and Azari'ah the son of Jehal'lelel; and of the Gershonites, Jo'ah the son of Zimmah, and Eden the son of Jo'ah; ¹³and of the sons of Eli-za'phan, Shimri and Jeu'el; and of the sons of Asaph, Zechari'ah and Mattani'ah; ¹⁴and of the sons of Heman, Jehu'el and Shim'e-i; and of the sons of Jedu'thun, Shemai'ah and Uz'ziel. ¹⁵They gathered their brethren, and sanctified themselves, and went in as the king had commanded, by the words of the LORD, to cleanse the house of the LORD. ¹⁶The 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. ¹⁷They 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; then for eight days they sanctified the house of the LORD, and on the sixteenth day of the first month they finished. ¹⁸Then they went in to Hezeki'ah 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. ¹⁹All the utensils which King Ahaz discarded in his reign when he was faithless, we have made ready and sanctified; and behold, they are before the altar of the LORD."
