2 Chronicles 29:15-31

When they had assembled their fellow Levites and consecrated themselves, they went in to purify the temple of the LORD, as the king had ordered, following the word of the LORD. The priests went into the sanctuary of the LORD to purify it. They brought out to the courtyard of the LORD’s temple everything unclean that they found in the temple of the LORD. The Levites took it and carried it out to the Kidron Valley. They began the consecration on the first day of the first month, and by the eighth day of the month they reached the portico of the LORD. For eight more days they consecrated the temple of the LORD itself, finishing on the sixteenth day of the first month. Then they went in to King Hezekiah and reported: “We have purified the entire temple of the LORD, the altar of burnt offering with all its utensils, and the table for setting out the consecrated bread, with all its articles. We have prepared and consecrated all the articles that King Ahaz removed in his unfaithfulness while he was king. They are now in front of the LORD’s altar.” Early the next morning King Hezekiah gathered the city officials together and went up to the temple of the LORD. They brought seven bulls, seven rams, seven male lambs and seven male goats as a sin offering for the kingdom, for the sanctuary and for Judah. The king commanded the priests, the descendants of Aaron, to offer these on the altar of the LORD. So they slaughtered the bulls, and the priests took the blood and splashed it against the altar; next they slaughtered the rams and splashed their blood against the altar; then they slaughtered the lambs and splashed their blood against the altar. The goats for the sin offering were brought before the king and the assembly, and they laid their hands on them. The priests then slaughtered the goats and presented their blood on the altar for a sin offering to atone for all Israel, because the king had ordered the burnt offering and the sin offering for all Israel. He stationed the Levites in the temple of the LORD with cymbals, harps and lyres in the way prescribed by David and Gad the king’s seer and Nathan the prophet; this was commanded by the LORD through his prophets. So the Levites stood ready with David’s instruments, and the priests with their trumpets. Hezekiah gave the order to sacrifice the burnt offering on the altar. As the offering began, singing to the LORD began also, accompanied by trumpets and the instruments of David king of Israel. The whole assembly bowed in worship, while the musicians played and the trumpets sounded. All this continued until the sacrifice of the burnt offering was completed. When the offerings were finished, the king and everyone present with him knelt down and worshiped. King Hezekiah and his officials ordered the Levites to praise the LORD with the words of David and of Asaph the seer. So they sang praises with gladness and bowed down and worshiped. Then Hezekiah said, “You have now dedicated yourselves to the LORD. Come and bring sacrifices and thank offerings to the temple of the LORD.” So the assembly brought sacrifices and thank offerings, and all whose hearts were willing brought burnt offerings.
