Then Hezekiah the king rose early,.... Took the first opportunity to attend the worship of God, and set an example to his people:

and gathered the rulers of the city; the elders of the people, the chief magistrates in Jerusalem:

and went up to the house of the Lord; the temple, to worship there.

The re-dedication of the temple by offering sacrifices. - 2 Chronicles 29:20. Probably on the very next morning Hezekiah went with the princes (heads) of the city into the house of the Lord, and brought seven bullocks, seven rams, and seven lambs for a burnt-offering, and seven he-goats for a sin-offering, "for the kingdom, for the sanctuary, and for Judah," i.e., as expiation for and consecration of the kingdom, sanctuary, and people. These sacrifices were offered by the priests according to the prescription of the law of Moses, 2 Chronicles 29:22-24. The burnt-offerings are first named, as in the sacrificial Torah in Leviticus 1-6, although the offering of the sin-offering preceded that of the burnt-offering. The laying on of hands, too, is mentioned only with the sin-offering, 2 Chronicles 29:23, although according to Leviticus 1:4 the same ceremony was gone through with the burnt-offerings; but that is not because a confession of sin was probably made during the laying on of hands, as Bertheau conjectures, adducing Leviticus 16:21, for from that passage no such conclusion can be drawn. The ceremony is mentioned only in the one case to emphasize the fact that the king and the assembly (the latter, of course, by their representatives) laid their hands upon the sacrificial beasts, because the atonement was, according to the king's words, to be for all Israel. "All Israel" are probably not only all the inhabitants of the kingdom of Judah, but Israelites in general (the twelve tribes), for whom the temple in Jerusalem was the only lawful sanctuary. דּם את חטּא signifies to bring the blood to the altar for an atonement, in the manner prescribed in Leviticus 4:30, Leviticus 4:34.

Then Hezekiah the king {h} rose early, and gathered the rulers of the city, and went up to the house of the LORD.

(h) By this manner of speech the Hebrews mean a certain diligence and speed to do a thing: and when there is no delay.

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.

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.
