I meant to ask about the nature of the people in the days of our Patriarchs and in our own day. In practice, we are defined as Jews and not as Hebrews, if only for the simple reason that conversion exists, and therefore any gentile can change his status and become a Jew—whether that gentile was originally barbarian, Slavic, or Germanic. Through conversion he joins both the people and the religion, which are things that cling together and cannot be separated.
Was conversion in the time of our forefather Abraham an attachment to both the people and the religion, as in our own day, or perhaps only to the religion, similar to Christianity, which is a universal religion and not a national one? Did the souls that were made in Haran become Hebrews?
P.S. I expect the Rabbi to answer on a historical or Torah basis, or in any other way…
This question came to me בעקבות the Canaanite/Hebrew movement of the 1940s

Of course my answer is no substitute for the Rabbi’s answers,
but from things I have read on this issue and this verse, it is commonly thought that the intention is that he brought them closer to observing the seven Noahide commandments and to believing in the one God—and therefore there is no reason to think that the souls they made became Hebrews or part of the Hebrew people, just as a gentile who observes the seven Noahide commandments today does not become a Hebrew, and certainly not a Jew.
