Albert Barnes Commentary 1 Chronicles 24:23

"And the sons [of Hebron]: Jeriah [the chief], Amariah the second, Jahaziel the third, Jekameam the fourth." — 1 Chronicles 24:23 (ASV)

Neither “Hebron” nor “the first” is found in the present Hebrew text; but they seem to have been rightly supplied by the translators from 1 Chronicles 23:19. The four persons named appear to have been contemporaries of David, the heads of the Hebronite houses in his time (compare 1 Chronicles 26:31).
