24 And the priests put them to death, and made a sin-offering with their blood on the altar, to take away the sin of all Israel: for the king gave orders that the burned offering and the sin-offering were for all Israel. 25 Then he put the Levites in their places in the house of the Lord, with brass and corded instruments of music as ordered by David and Gad, the king's seer, and Nathan the prophet: for the order was the Lord's, given by his prophets. 26 So the Levites took their places with David's instruments, and the priests with their horns.

Commentary on 2 Chronicles 29:20-36
(Read 2 Chronicles 29:20-36)
As soon as Hezekiah heard that the temple was ready, he lost no time. Atonement must be made for the sins of the last reign. It was not enough to lament and forsake those sins; they brought a sin-offering. Our repentance and reformation will not obtain pardon but in and through Christ, who was made sin, that is, a sin-offering for us. While the offerings were on the altar, the Levites sang. Sorrow for sin must not prevent us from praising God. The king and the congregation gave their consent to all that was done. It is not enough for us to be where God is worshipped, if we do not ourselves worship with the heart. And we should offer up our spiritual sacrifices of praise and thanksgiving, and devote ourselves and all we have, as sacrifices, acceptable to the Father only through the Redeemer.
