31 Then Hezekiah said, "You have now consecrated yourselves to[1] the Lord. Come near; bring sacrifices and thank offerings to the house of the Lord." And the assembly brought sacrifices and thank offerings, and all who were of a willing heart brought burnt offerings. 32 The number of the burnt offerings that the assembly brought was 70 bulls, 100 rams, and 200 lambs; all these were for a burnt offering to the Lord. 33 And the consecrated offerings were 600 bulls and 3,000 sheep. 34 But the priests were too few and could not flay all the burnt offerings, so until other priests had consecrated themselves, their brothers the Levites helped them, until the work was finished-- for the Levites were more upright in heart than the priests in consecrating themselves. 35 Besides the great number of burnt offerings, there was the fat of the peace offerings, and there were the drink offerings for the burnt offerings. Thus the service of the house of the Lord was restored.

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.
