Matthew Poole and continuators on Joshua 7:17

17 And he brought the family of Judah, and he took the family of the Zarhites: and he brought the family of the Zarhites, man by man , and Zabdi was taken.

Either, 1. the Tribe or people, as the word Family sometimes signifies, as Iudg. 13. 2. Zech. 12. 13. Amos 3. 1. Act. 3. 25. compared with Revel. 1. 7. Or, 2. the Families, as v. 14. the singular Number for the plural, the chief of each of their five Families, Numb. 26. 20, 21.

Not every individual person, as is evident from v. 18. but every Head of the several Houses, or lesser Families of that greater Family of the Zarhites, of which see 1 Chron. 2. 6.
