2 Chronicles 29:20-30

20Early the next morning King Hezekiah gathered the city officials together and went up to the temple of the LORD . 21They brought seven bulls, seven rams, seven male lambs and seven male goats as a sin offering Or purification offering; also in verses 23 and 24 for the kingdom, for the sanctuary and for Judah. The king commanded the priests, the descendants of Aaron, to offer these on the altar of the LORD . 22So they slaughtered the bulls, and the priests took the blood and splashed it against the altar; next they slaughtered the rams and splashed their blood against the altar; then they slaughtered the lambs and splashed their blood against the altar. 23The goats for the sin offering were brought before the king and the assembly, and they laid their hands on them.

24The priests then slaughtered the goats and presented their blood on the altar for a sin offering to atone for all Israel, because the king had ordered the burnt offering and the sin offering for all Israel. 25He stationed the Levites in the temple of the LORD with cymbals, harps and lyres in the way prescribed by David and Gad the king’s seer and Nathan the prophet; this was commanded by the LORD through his prophets.

26So the Levites stood ready with David’s instruments, and the priests with their trumpets. 27Hezekiah gave the order to sacrifice the burnt offering on the altar. As the offering began, singing to the LORD began also, accompanied by trumpets and the instruments of David king of Israel.

28The whole assembly bowed in worship, while the musicians played and the trumpets sounded. All this continued until the sacrifice of the burnt offering was completed. 29When the offerings were finished, the king and everyone present with him knelt down and worshiped.

30King Hezekiah and his officials ordered the Levites to praise the LORD with the words of David and of Asaph the seer. So they sang praises with gladness and bowed down and worshiped.
