And these are they whom David set over the service of song in the house of the LORD, after that the ark had rest.
These are they whom David set over the service of song. The sons of Korah, Asaph, Heman, Jeduthun or Ethan (Psalms 89:1-52), were set over the various departments of the musical services of the sanctuary.
In the house of the Lord - i:e., in the tent which David had erected for receiving the ark after it was removed from the house of Obed-edom. This was a considerable time before the temple was built. This institution, as appears, 1 Chronicles 6:32, was originally intended to continue only until the erection of the temple; but its advantages were found to be so great as to ensure its permanent continuance (2 Chronicles 35:15) and it was revived after the restoration from Babylon (Nehemiah 12:45-46).
