20 Then Hezekiah the king went to work: He got all the leaders of the city together and marched to The Temple of God. 21 They brought with them seven bulls, seven rams, seven lambs, and seven he-goats to sacrifice as an Absolution-Offering for the royal family, for the Sanctuary, and for Judah as a whole; he directed the Aaronite priests to sacrifice them on the Altar of God. 22 The priests butchered the bulls and then took the blood and sprinkled it on the Altar, and then the same with the rams and lambs. 23 Finally they brought the goats up; the king and congregation laid their hands upon them. 24 The priests butchered them and made an Absolution-Offering with their blood at the Altar to atone for the sin of all Israel - the king had ordered that the Whole-Burnt-Offering and the Absolution-Offering be for all Israel. 25 The king ordered the Levites to take their places in The Temple of God with their musical instruments - cymbals, harps, zithers - following the original instructions of David, Gad the king's seer, and Nathan the prophet; this was God's command conveyed by his prophets. 26 The Levites formed the orchestra of David, while the priests took up the trumpets. 27 Then Hezekiah gave the signal to begin: The Whole-Burnt-Offering was offered on the Altar; at the same time the sacred choir began singing, backed up by the trumpets and the David orchestra 28 while the entire congregation worshiped. The singers sang and the trumpeters played all during the sacrifice of the Whole-Burnt-Offering. 29 When the offering of the sacrifice was completed, the king and everyone there knelt to the ground and worshiped.

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.
