21 Lo! the partings of priests and of deacons, into all the work of the service of the house of the Lord, shall stand nigh [to] thee; and they be ready to do their service, and both the princes and the people know to do all thy commandments. (Lo! the divisions of the priests, and the Levites, shall do their duties, ready to do all the work in the service of the House of the Lord; and all the craftsmen be ready to do their service; and also the leaders, and all the people, shall be wholly at thy command.)

1 Chronicles 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.

1 Chronicles 28:21 In-Context

19 And David said, All (these) things came written by the hand of the Lord to me, that I should understand all the works of the exemplar/of the ensampler (so that I could understand all the works in the example).

20 And David said to Solomon, his son, Do thou manly, and be thou comforted, and make; dread thou not withoutforth, neither dread thou within; for my Lord God shall be with thee, and he shall not leave thee, neither shall forsake thee, till thou perform all the work of the service of the house of the Lord. (And David said to his son Solomon, Be thou confident, and be thou strengthened, and make it; fear thou not anything from withoutforth, nor fear thou anything from within; for the Lord my God shall be with thee, and he shall not leave thee, nor shall desert thee, until thou finish all the work needed in the service of the House of the Lord.)
