So anyone circumcising their children is an heir? And I would argue they do not do so as Torah commands.
Daughters which were heirs, as there was no male to pass it to, were to marry into the tribe of their father.......
Nu 36:7 So shall not the inheritance of the children of Israel remove from tribe to tribe:
Nu 36:8 And every daughter, that possesseth an inheritance in any tribe of the children of Israel, shall be wife unto one of the family of the tribe of her father, that the children of Israel may enjoy every man the inheritance of his fathers.
Nu 36:9 Neither shall the inheritance remove from one tribe to another tribe; but
every one of the tribes of the children of Israel shall keep himself to his own inheritance.
Tribal affiliation through children. Intermarriage
Ez 47:21 So shall ye divide this land unto you
according to the tribes of Israel.
22 And it shall come to pass, that ye shall divide it by lot for an inheritance unto you
, and to the strangers that sojourn among you, which shall beget children among you: and they shall be unto you as born in the country among the children of Israel; they shall have inheritance with you among the tribes of Israel.
23 And it shall come to pass, that
in what tribe the stranger sojourneth, there shall ye give him his inheritance, saith the Lord GOD.
Ezek 47:22 And it shall come to pass, that ye shall divide it by lot for an inheritance unto you, and to the strangers that sojourn among you, which shall beget children among you: and they shall be unto you as born in the country among the children of Israel; they shall have inheritance with you among the tribes of Israel.
