Verse 16: So Joshua rose up early in the morning, and brought Israel by their tribes; and the tribe of Judah was taken…
[It was found] Understanding, to have withheld from the anathema (Vatablus).
Verse 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…
[According to their families] Hebrew: the family of Judah, that is, the Tribe. Thus Judges 13:2, the family of the Danites; Acts 3:25, πᾶσαι αἱ πατριαὶ τῆς γῆς, all the kindreds of the earth, that is, families; and elsewhere, the family which thou leddest out of Egypt (Drusius).
The family of Judah; either, 1. The tribe or people, as the word family sometimes signifies, as Judges 13:2; Zechariah 12:13; Amos 3:1; Acts 3:25, compared with Revelation 1:7. Or, 2. The families, as Joshua 7:14, the singular number for the plural, the chief of each of their five families, Numbers 26:20, 21. Man by man; not every individual person, as is evident from Joshua 7:18, but every head of the several houses or lesser families of that greater family of the Zarhites, of which see 1 Chronicles 2:6.
Verse 18: And he brought his household man by man; and Achan, the son of Carmi, the son of Zabdi, the son of Zerah, of the tribe of Judah, (1 Sam. 14:42) was taken.
He; either Joshua, or Zabdi by Joshua’s appointment.
[Dividing into individual men, לַגְּבָרִים] Man by man, that is, by the houses of the fathers (Drusius). It signifies the leaders of the families (Vatablus).

 Hebrew: אֶת־מִשְׁפַּ֣חַת יְהוּדָ֔ה.
