2 Chronicles 29:16-26

16 The priests went into the inner part of the house of the LORD to cleanse it, and they 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 and carried it out to the brook Kidron.
17 They began to sanctify on the first day of the first month, and on the eighth day of the month they came to the vestibule of the LORD; then for eight days they sanctified the house of the LORD, and on the sixteenth day of the first month they finished.
18 Then they went in to Hezeki'ah the king and said, "We have cleansed all the house of the LORD, the altar of burnt offering and all its utensils, and the table for the showbread and all its utensils.
19 All the utensils which King Ahaz discarded in his reign when he was faithless, we have made ready and sanctified; and behold, they are before the altar of the LORD."
20 Then Hezeki'ah the king rose early and gathered the officials of the city, and went up to the house of the LORD.
21 And they brought seven bulls, seven rams, 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 bulls, and the priests received the blood and threw it against the altar; and they killed the rams and their blood was thrown against the altar; and they killed the lambs and their blood was thrown against the altar.
23 Then the he-goats for the sin offering were brought to the king and the assembly, and they laid their hands upon them,
24 and the priests killed them and made a sin offering with their blood on 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.
25 And he stationed the Levites in the house of the LORD with cymbals, harps, and lyres, according to the commandment of David and of Gad the king's seer and of Nathan the prophet; for the commandment was from the LORD through his prophets.
26 The Levites stood with the instruments of David, and the priests with the trumpets.
