2 Chronicles 29:29-31

When the offerings were finished, the king and everyone present with him knelt down and worshiped. King 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. Then Hezekiah said, “You have now dedicated yourselves to the LORD. Come and bring sacrifices and thank offerings to the temple of the LORD.” So the assembly brought sacrifices and thank offerings, and all whose hearts were willing brought burnt offerings.
