2 Chronicles 29:13-30

13and of the sons of Elizaphan, Shimri and Jeuel: and of the sons of Asaph, Zechariah and Mattaniah:

14and of the sons of Heman, Jehuel and Shimei: and of the sons of Jeduthun, Shemaiah and Uzziel.

15And they gathered their brethren, and sanctified themselves, and went in, according to the commandment of the king by the words of the LORD, to cleanse the house of the LORD.

16And the priests went in unto 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 to the brook Kidron.

17Now they began on the first day of the first month to sanctify, and on the eighth day of the month came they to the porch of the LORD; and they sanctified the house of the LORD in eight days: and on the sixteenth day of the first month they made an end.

18Then they went in to Hezekiah the king within the palace, and said, We have cleansed all the house of the LORD, and the altar of burnt offering, with all the vessels thereof, and the table of shewbread, with all the vessels thereof.

19Moreover all the vessels, which king Ahaz in his reign did cast away when he trespassed, have we prepared and sanctified; and, behold, they are before the altar of the LORD.

20Then Hezekiah the king arose early, and gathered the princes of the city, and went up to the house of the LORD.

21And they brought seven bullocks; and seven rams, and seven lambs, and seven he-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 bullocks, and the priests received the blood, and sprinkled it on the altar: and they killed the rams, and sprinkled the blood upon the altar: they killed also the lambs, and sprinkled the blood upon the altar.

23And they brought near the he-goats for the sin offering before the king and the congregation; and they laid their hands upon them:

24and the priests killed them, and they made a sin offering with their blood upon the altar, to make 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 the commandment was of the LORD by his prophets.

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, and the trumpets, together with the instruments of David king of Israel.

28And all the congregation worshipped, and the singers sang, and the trumpeters sounded; all this continued until the burnt offering was finished.

29And when they had made an end of offering, the king and all that were present with him bowed themselves and worshipped.

30Moreover Hezekiah the king and the princes commanded the Levites to sing praises unto 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.
