After the ordinance of David, king of Israel. — All goes back to earlier times. As the first offerings on the altar were according to what was “written in the law of Moses, the man of God,” so the musical ceremonial of this foundation is according to the precedent of David (see 1 Chronicles 6; 1 Chronicles 16:25). The trumpets belonged to the priests, the cymbals to the Levites, in the ancient ordinances of worship.
