31 Then Hezekiah declared, "Now that you have consecrated yourselves to the Lord, bring your sacrifices and thanksgiving offerings to the Temple of the Lord ." So the people brought their sacrifices and thanksgiving offerings, and all whose hearts were willing brought burnt offerings, too. 32 The people brought to the Lord 70 bulls, 100 rams, and 200 male lambs for burnt offerings. 33 They also brought 600 cattle and 3,000 sheep and goats as sacred offerings. 34 But there were too few priests to prepare all the burnt offerings. So their relatives the Levites helped them until the work was finished and more priests had been purified, for the Levites had been more conscientious about purifying themselves than the priests had been. 35 There was an abundance of burnt offerings, along with the usual liquid offerings, and a great deal of fat from the many peace offerings. So the Temple of the Lord was restored to service.

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.
