21:10 Which the children of {d} Aaron, [being] of the families of the Kohathites, [who were] of the children of Levi, had: for theirs was the first lot.
(d) For Aaron came from Kohath, and therefore the priests office remained in that family.
21:10 Families - That is, of the family, the plural number for the singular, which is not unusual.
21:9-42 By mixing the Levites with the other tribes, they were made to see that the eyes of all Israel were upon them, and therefore it was their concern to walk so that their ministry might not be blamed. Every tribe had its share of Levites' cities. Thus did God graciously provide for keeping up religion among them, and that they might have the word in all parts of the land. Yet, blessed be God, we have the gospel more diffused amongst us.
