2 Chronicles 29:13-30

13and from the sons of Elizaphan, Shimri and 1Jeiel; and from the sons of Asaph, Zechariah and Mattaniah; 14and from the sons of Heman, 2Jehiel and Shimei; and from the sons of Jeduthun, Shemaiah and Uzziel. 15They assembled their brothers, 3consecrated themselves, and went in 4to cleanse the house of the Lord, according to the commandment of the king 5by the words of the Lord. 16So the priests went into the inner part of the house of the Lord to cleanse it, and they brought every unclean thing which they found in the temple of the Lord out to the courtyard of the house of the Lord. Then the Levites received it to carry out to 6the Kidron 7Valley. 17Now they began 8the consecration 9on the first day of the first month, and on the eighth day of the month they entered the porch of the Lord. Then they consecrated the house of the Lord in eight days, and finished on the sixteenth day of the first month. 18Then they went in to King Hezekiah and said, “We have cleansed the whole house of the Lord, the altar of burnt offering with all its utensils, and the table of the showbread with all of its utensils. 19Moreover, 10all the utensils which King Ahaz had discarded during his reign in his unfaithfulness, we have prepared and consecrated; and behold, they are before the altar of the Lord.”

20Then King Hezekiah got up early and assembled the princes of the city, and went up to the house of the Lord. 21They brought seven bulls, seven rams, seven lambs, and seven male goats 11as a sin offering for the kingdom, the sanctuary, and Judah. And he ordered the priests, the sons of Aaron, to offer them on the altar of the Lord. 22So they slaughtered the bulls, and the priests took the blood and sprinkled it on the altar. They also slaughtered the rams and sprinkled the blood on the altar; they slaughtered the lambs as well, and 12sprinkled the blood on the altar. 23Then they brought the male goats of the sin offering before the king and the assembly, and 13they laid their hands on them. 24The priests slaughtered them and purified the altar with their blood 14to atone for all Israel, because the king ordered the burnt offering and the sin offering for all Israel.

2515He then stationed the Levites in the house of the Lord with cymbals, harps, and lyres, 16according to the command of David and of 17Gad, the king’s seer, and of 18Nathan the prophet; for the command was from the Lord through His prophets. 26The Levites stood with 19the musical instruments of David, and 20the priests with the trumpets. 27Then Hezekiah gave the order to offer the burnt offering on the altar. When the burnt offering began, 21the song to the Lord also began with the trumpets, 22accompanied by the instruments of David, king of Israel. 28While the whole assembly worshiped, the singers also sang and the trumpets sounded; all this continued until the burnt offering was finished.

29Now at the completion of the burnt offerings, 23the king and all who were present with him bowed down and worshiped. 30Moreover, King Hezekiah and the officials ordered the Levites to sing praises to the Lord with the words of David and Asaph the seer. 24So they sang praises with joy, and bowed down and worshiped.
