21 They brought seven bulls, seven rams, seven lambs and seven male goats for a sin offering for the kingdom, the sanctuary, and Judah. And he ordered the priests, the sons of Aaron, to offer them on the altar of the Lord.
22 So they slaughtered the bulls, and the priests took the blood and sprinkled it on the altar. They also slaughtered the rams and sprinkled the blood on the altar; they slaughtered the lambs also and sprinkled the blood on the altar.
23 Then they brought the male goats of the sin offering before the king and the assembly, and they laid their hands on them.
24 The priests slaughtered them and purged the altar with their blood to atone for all Israel, for the king ordered the burnt offering and the sin offering for all Israel.
25 He then stationed the Levites in the house of the Lord with cymbals, with harps and with lyres, according to the command of David and of Gad the king's seer, and of Nathan the prophet; for the command was from the Lord through His prophets.
26 The Levites stood with the musical instruments of David, and the priests with the trumpets.
27 Then Hezekiah gave the order to offer the burnt offering on the altar. When the burnt offering began, the song to the Lord also began with the trumpets, accompanied by the instruments of David, king of Israel.
