2 Chronicles 29:4-11, 30

Then he brought in the priests and Levites and gathered them in the eastern public square.  He said to them, “Hear me, Levites. Consecrate yourselves  now and consecrate the temple of the LORD, the God of your ancestors. Remove everything impure from the holy place. For our ancestors were unfaithful and did what is evil in the sight of the LORD our God. They abandoned him, turned their faces away from the LORD’s dwelling place, and turned their backs on him.  , They also closed the doors of the portico, extinguished the lamps, did not burn incense, and did not offer burnt offerings in the holy place of the God of Israel. Therefore, the wrath of the LORD was on Judah and Jerusalem, and he made them an object of terror, horror, and mockery,  , as you see with your own eyes. Our fathers fell by the sword, and our sons, our daughters, and our wives are in captivity because of this.  It is in my heart now to make a covenant with the LORD, the God of Israel  so that his burning anger may turn away from us. My sons, don’t be negligent now, for the LORD has chosen you to stand in his presence, to serve him, and to be his ministers and burners of incense.”

Then King Hezekiah and the officials told the Levites to sing praise to the LORD in the words of David and of the seer Asaph. So they sang praises with rejoicing and knelt low and worshiped.
