Divrey Hayamim Alef 28:21 Meaning and Commentary

1 Chronicles 28:21

And, behold, all the courses of the priests and the Levites,
&c.] Which David had lately fixed to take their turns in the temple, when built: even they shall be with thee

for all the service of the house of God;
to advise and assist him in everything relating to the service of the sanctuary, which they might be supposed best to understand:

and there shall be with thee, for all manner of workmanship, every
willing skilful man for any manner of service;
men that were not only well skilled in all manner of curious work that was necessary for the service of the house, but were willing to employ their skill to the uttermost for it, and such David had provided, ( 1 Chronicles 22:15 ) ,

also the princes and all the people will be wholly at thy commandment:
to do whatever he should order, whether to overlook the workmen, or to contribute to the expenses of the work.
