Notes on the Bible, by Albert Barnes, [1834], at sacred-texts.com
Compare Sa2 6:1-11 and notes.
The captains ... - Such an organisation had probably been established generally through the tribes prior to the time of David: but David seems to have been the first to recognize in these officers of the host representatives of the people, to consult them on public affairs, and to give them a certain political position.
Shihor - See the marginal reference and the Kg1 8:65 note.
