The chief fathers. The same phrase is more correctly translated in Exodus 6:25 "heads of the fathers." It is, however, probable that הָאָבור (fathers) is a contraction for בֵּית־הַאָבוֹת (fathers' houses).
The fathers' house was the next recognized and familiar division below the mishpachah (family). Probably the fathers' house included originally all the descendants of a living ancestor, who formed the bond of union between them; but this union no doubt survived in many cases the death of the common ancestor, whose authority would then devolve upon the oldest efficient member of the house.
The families of the children of Gilead. "The mishpachoth of the Beni-Gilead" certainly did not include the Machirites, who were somewhat sharply distinguished from the other Manassites (see above on Numbers 26:29; Numbers 32:39 ff.
); it is even doubtful whether they included the Gileadites proper, who took their name (and perhaps traced their descent) from Gilead, but not from his sons. It may be confidently assumed that the Machirites, who had received an extensive and remote territory beyond Jordan, had nothing whatever to do with this application.
It was the other section of the tribe, the mishpachoth of the six sons of Gilead, who were yet to receive inheritance by lot in Canaan proper, to whom the matter appeared so serious that they came to Moses about it.
