Numbers 36:12 Meaning and Commentary

Numbers 36:12

And they were married into the families of the sons of
Manasseh, the son of Joseph
The family of the Hepherites, of which they were. Aben Ezra observes, that their being married into families, and not a family, is a sign that their uncles' sons were not all of them brethren, or the sons of one man, but of more, though all sons of one or other of their father's, brethren:

and their inheritance remained in the tribe of the family of their
father;
by means of these marriages, even both in their father's tribe and family.
