'Grouped' in the Bible

Jahath was the chief and Zizah the second; but Jeush and Beriah had only a small number of sons, so they were grouped together as one family.

These were the sons of Levi, grouped by families, the heads of the families of those who were numbered by name, by heads, all those of twenty years old and over who did the work of the house of the Lord.

Now the divisions into which the sons of Aaron were grouped were these: the sons of Aaron, Nadab and Abihu, Eleazar and Ithamar.

And there were more chiefs among the sons of Eleazar than among the sons of Ithamar; and this is how they were grouped: of the sons of Eleazar there were sixteen, all heads of families; and of the sons of Ithamar, heads of families, there were eight.
