20 Then King Hezekiah arose early and assembled the princes of the city and went up to the house of the Lord . 21 They brought seven bulls , seven rams , seven lambs and seven male goats for 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 . 22 So 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 also and sprinkled the blood on the altar . 23 Then they brought the male goats of the sin offering before the king and the assembly , and they laid their hands on them. 24 The priests slaughtered them and purged the altar with their blood to atone for all Israel , for the king ordered the burnt offering and the sin offering for all Israel . 25 He then stationed the Levites in the house of the Lord with cymbals , with harps and with lyres , according to the command of David and of Gad the king's seer , and of Nathan the prophet ; for the command was from the Lord through His prophets . 26 The Levites stood with the musical instruments of David , and the priests with the trumpets . 27 Then Hezekiah gave the order to offer the burnt offering on the altar . When the burnt offering began , the song to the Lord also began with the trumpets , accompanied by the instruments of David , king of Israel . 28 While the whole assembly worshiped , the singers also sang and the trumpets sounded ; all this continued until the burnt offering was finished . 29 Now at the completion of the burnt offerings , the king and all who were present with him bowed down and worshiped .

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.
