John Gill Commentary 1 Chronicles 6:32

"And they ministered with song before the tabernacle of the tent of meeting, until Solomon had built the house of Jehovah in Jerusalem: and they waited on their office according to their order." — 1 Chronicles 6:32 (ASV)

And they ministered before the dwelling place of the
tabernacles of the congregation with singing
Psalms, hymns, and spiritual songs; this service they performed before the ark, which was in a tent or tabernacle David pitched for it; and which the Targum here calls the tabernacle of time, or a temporary tabernacle:

until Solomon had built the house of the Lord in Jerusalem ;
the temple there:

and then they waited on their office according to their order ;
performed it in the manner prescribed by David, see (1 Chronicles 25:1–31) .
