Chronicles II 29:25 Meaning and Commentary

2 Chronicles 29:25

And he set the Levites in the house of the Lord with cymbals,
with psalteries, and with harps
To play upon, which were the three principal instruments of music used in religious worship, and what had been disused in the times of Ahaz: according to the commandment of David, and of Gad the king's seer, and
Nathan the prophet;
this sort of music was not commanded by the law of Moses, but was directed to by David under a divine influence, and was approved of by the prophets of the Lord here mentioned: for so was the commandment of the Lord by his prophets;
the Targum is,

``for by the Word of the Lord was the commandment by the hand of the prophets.''
