Neither “Hebron” nor “the first” is found in the present Hebrew text; but they seem to have been rightly supplied by our 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).
