2 Chronicles 29:27

And when Ezekias gave orders to carry up the whole burnt offering on the altar, and they began to carry it up, the musicians began the song of praise to the Lord, and the trumpets sounded in concert with the musical instruments of David king of Israel,

And Ezekias told them to offer up the whole-burnt-offering on the altar: and when they began to offer the whole-burnt-offering, they began to sing to the Lord, and the trumpets accompanied the instruments of David king of Israel.
