Passage
and all the heads, and the mighty men, and also all the sons of king David have given a hand under Solomon the king;
and all the heads, and the mighty men, and also all the sons of king David have given a hand under Solomon the king;
1 Chronicles 29:22 And they eat and drink before Jehovah on that day with great joy, and cause Solomon son of David to reign a second time, and anoint <FI>him<Fi> before Jehovah for leader, and Zadok for priest.
1 Chronicles 29:23 And Solomon sitteth on the throne of Jehovah for king instead of David his father, and prospereth, and all Israel hearken unto him,
1 Chronicles 29:24 and all the heads, and the mighty men, and also all the sons of king David have given a hand under Solomon the king;
1 Chronicles 29:25 and Jehovah maketh Solomon exceedingly great before the eyes of all Israel, and putteth upon him the honour of the kingdom that hath not been on any king over Israel before him.
1 Chronicles 29:26 And David son of Jesse hath reigned over all Israel,
The verse centers on "heads", "mighty", "sons", "king", "david", "given", "hand", and "under". It is saying that the verse draws attention to "heads" and "mighty", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 23's "And Solomon sitteth on the throne of..." into verse 25's "and Jehovah maketh Solomon exceedingly great before...", so "heads" and "mighty" belong inside that flow. In 1 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "heads" and "mighty" with trust shaped by these words, not by a vague optimism outside the passage.
