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.
20-30. Then Hezekiah the king rose early, and gathered the rulers of the city—His anxiety to enter upon the expiatory service with all possible despatch, now that the temple had been properly prepared for it, prevented his summoning all the representatives of Israel. The requisite number of victims having been provided, and the officers of the temple having sanctified themselves according to the directions of the law, the priests were appointed to offer sacrifices of atonement successively, for "the kingdom," that is, for the sins of the king and his predecessors; for "the sanctuary," that is, for the sins of the priests themselves and for the desecration of the temple; "and for Judah," that is, for the people who, by their voluntary consent, were involved in the guilt of the national apostasy. Animals of the kinds used in sacrifice were offered by sevens, that number indicating completeness. The Levites were ordered to praise God with musical instruments, which, although not originally used in the tabernacle, had been enlisted in the service of divine worship by David on the advice of the prophets Gad and Nathan, as well calculated to animate the devotions of the people. At the close of the special services of the occasion, namely, the offering of atonement sacrifices, the king and all civic rulers who were present joined in the worship. A grand anthem was sung (2Ch 29:30) by the choir, consisting of some of the psalms of David and Asaph, and a great number of thank offerings, praise offerings, and freewill burnt offerings were presented at the invitation of the king.
