2 Chronicles 29:25-30

25And he stationed the Levites in the house of the LORD with cymbals, harps, and lyres, according to the commandment of David and of Gad the king’s seer and of Nathan the prophet, for the commandment was from the LORD through his prophets. 26The Levites stood with the instruments of David, and the priests with the trumpets. 27Then Hezekiah commanded that the burnt offering be offered on the altar. And when the burnt offering began, the song to the LORD began also, and the trumpets, accompanied by the instruments of David king of Israel. 28The whole assembly worshiped, and the singers sang, and the trumpeters sounded. All this continued until the burnt offering was finished. 29When the offering was finished, the king and all who were present with him bowed themselves and worshiped. 30And Hezekiah the king and the officials commanded the Levites to sing praises to the LORD with the words of David and of Asaph the seer. And they sang praises with gladness, and they bowed down and worshiped.
