2 Chronicles 29:25-28

CLV(i) 25 And he appoints the Levites in the house of Yahweh with cymbals, with psalteries, and with harps, by the command of David, and of Gad, seer of the king, and of Nathan the prophet, for by the hand of Yahweh [is] the command, by the hand of His prophets;" 26 and the Levites stand with the instruments of David, and the priests with the trumpets. 27 And Hezekiah said to cause the burnt-offering to ascend on the altar; and at the time the burnt-offering began--began the song of Yahweh, and the trumpets, even by the hands of the instruments of David king of Israel. 28 And all the assembly are doing obeisance, and the singers singing, and the trumpeters blowing; the whole [is] till the completion of the burnt-offering.
