John Gill Commentary 1 Chronicles 15:25

"So David, and the elders of Israel, and the captains over thousands, went to bring up the ark of the covenant of Jehovah out of the house of Obed-edom with joy." — 1 Chronicles 15:25 (ASV)

So David and the elders of Israel, and the captains over
thousands
He and the principal men of the nation, and the officers of the army or militia:

went to bring up the ark of the covenant of the Lord out of the house
of Obededom with joy ;
with all demonstrations of it; for which purpose such a band of music was prepared, as before described.
