2 Chronicles 29:25-28

29:25 And he set the Levites in the house of the LORD with cymbals, with psalteries, and with harps, according to the commandment of David, and of Gad the king’s seer, and Nathan the prophet: for [so was] the commandment of the LORD by his prophets. 29:26 And the Levites stood with the instruments of David, and the priests with the trumpets. 29:27 And Hezekiah commanded to offer the burnt offering upon the altar. And when the burnt offering began, the song of the LORD began [also] with the trumpets, and with the instruments [ordained] by David king of Israel. 29:28 And all the congregation worshipped, and the singers sang, and the trumpeters sounded: [and] all [this continued] until the burnt offering was finished.
