1 Chronicles 7:7

(7) And the sons of Bela.—The names are wholly different in 1 Chronicles 8:3-4. The reason would seem to be that the names before us represent the chieftains and clans of Bela as they existed at a given epoch, viz., the time of David’s census. The list of 1 Chronicles 8:0 belongs to another period. Here, as elsewhere, it is evident enough that the chronicler has faithfully followed or rather transcribed his sources, without a thought of harmonising their apparent inconsistencies.

Heads of . . . fathers.—Rather, heads of their father-houses, i.e., chieftains.

And were reckoned by their genealogies.—And their census was 22,034. This number represents the fighting strength of the Belaites,. who are here identified with their heads.
