2 Chronicles 29:13-30

13And of the sons of Elizaphan; Shimri, and Jeiel: and of the sons of Asaph; Zechariah, and Mattaniah: 14And of the sons of Heman; Jehiel, and Shimei: and of the sons of Jeduthun; Shemaiah, and Uzziel. 15And they assembled their brethren, and sanctified themselves, and came, according to the commandment of the king, by the words of the LORD, to cleanse the house of the LORD.1 16And the priests went into the inner part of the house of the LORD, to cleanse it, and 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, to carry it out abroad into the brook Kidron. 17Now they began on the first day of the first month to sanctify, and on the eighth day of the month they came to the porch 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. 18Then they went in to Hezekiah the king, and said, We have cleansed all the house of the LORD, and the altar of burnt offering, with all its vessels, and the showbread table, with all its vessels. 19Moreover all the vessels, which king Ahaz in his reign cast away in his transgression, have we prepared and sanctified, and, behold, they are before the altar of the LORD.

20Then Hezekiah the king rose early, and assembled the rulers of the city, and went up to the house of the LORD. 21And they brought seven bulls, and seven rams, and seven lambs, and seven male goats, for a sin offering for the kingdom, and for the sanctuary, and for Judah. And he commanded the priests the sons of Aaron to offer them on the altar of the LORD. 22So they killed the bulls, and the priests received the blood, and sprinkled it on the altar: likewise, when they had killed the rams, they sprinkled the blood upon the altar: they killed also the lambs, and they sprinkled the blood upon the altar. 23And they brought forth the male goats for the sin offering before the king and the congregation; and they laid their hands upon them:2 24And the priests killed them, and they made reconciliation with their blood upon the altar, to make an atonement for all Israel: for the king commanded that the burnt offering and the sin offering should be made for all Israel. 25And he set the Levites in the house of the LORD with cymbals, with psalteries, and with harps, according to the commandment of David, and of Gad the king’s seer, and Nathan the prophet: for so was the commandment of the LORD by his prophets.34 26And the Levites stood with the instruments of David, and the priests with the trumpets. 27And Hezekiah commanded to offer the burnt offering upon the altar. And when the burnt offering began, the song of the LORD began also with the trumpets, and with the instruments ordained by David king of Israel.56 28And all the congregation worshipped, and the singers sang, and the trumpeters sounded: and all this continued until the burnt offering was finished.7 29And when they had finished offering, the king and all that were present with him bowed themselves, and worshipped.8 30Moreover Hezekiah the king and the princes commanded the Levites to sing praise to the LORD with the words of David, and of Asaph the seer. And they sang praises with gladness, and they bowed their heads and worshipped.
