John Wesley on Joshua 7:17

The family - Either, the tribe or people, as the word family sometimes signifies, or, the families, as ver. 14, the singular number for the plural, the chief of each of their five families, Numb 26:20,21. Man by man - Not every individual person, as is evident from Jos 7:18, but every head of the several houses, or lesser families of that greater family of the Zarhites, of which see 1Chron 2:6.
