2 Chronicles 29:18-28

18 Then 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 the vessels thereof, and the shewbread table, with all the vessels thereof.
19 Moreover all the vessels, which king Ahaz in his reign did cast away in his transgression, have we prepared and sanctified, and, behold, they are before the altar of the LORD.
20 Then Hezekiah the king rose early, and gathered the rulers of the city, and went up to the house of the LORD.
21 And 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.
22 So they killed the bullocks, 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.
23 And they brought fortha the he goats for the sin offering before the king and the congregation; and they laid their hands upon them:
24 And 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.
25 And 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.
26 And the Levites stood with the instruments of David, and the priests with the trumpets.
27 And Hezekiah commanded to offer the burnt offering upon the altar. And whenb the burnt offering began, the song of the LORD began also with the trumpets, and with the instruments ordained by David king of Israel.
28 And all the congregation worshipped, and the singersc sang, and the trumpeters sounded: and all this continued until the burnt offering was finished.
