Charles Ellicott Commentary 1 Chronicles 7:11

"All these were sons of Jediael, according to the heads of their fathers` [houses], mighty men of valor, seventeen thousand and two hundred, that were able to go forth in the host for war." — 1 Chronicles 7:11 (ASV)

All these the sons of Jediael. —Render, “All these were sons of Jediael; (according) to the heads of the clans, valiant warriors; 17,200 going out in force to battle.” Perhaps the particle (according to) should be omitted. In any case, the chiefs or the clans are regarded as one with their warriors.

The sum of the warriors of Benjamin is thus 54,434. The Mosaic census (Numbers 26:41) gave 45,600. An increase of barely 14,000 in the course of at least three centuries may seem too small. But the tribe was nearly exterminated in the vengeance which Israel took for the crime of Gibeah (Judges 20:47).
