2 Chronicles 29:26-28

Young's Literal Translation

²⁶ and the Levites stand with the instruments of David, and the priests with the trumpets.

²⁷ And Hezekiah saith to cause the burnt-offering to ascend on the altar; and at the time the burnt-offering began -- began the song of Jehovah, 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.
