1 Chronicles 7:40 Meaning and Commentary

1 Chronicles 7:40

All these were the children of Asher, heads of their father's
house
Principal men in their tribe, and respective families:

choice and mighty men of valour;
these were some selected from others, being eminent for their courage and valour:

chief of the princes;
or chief princes; the Vulgate Latin version is, dukes of dukes, they were heads of their fathers' families:

[and] the number throughout the genealogy that were apt to war, and to
battle, [was] twenty and six thousand [men];
that is, in the days of David, ( 1 Chronicles 7:4 ) , this was the number, not of their chief men, nor of all the people in the tribe, but of their militia.
