I read in the Book of Isaiah (Is. 56:1-8), about the foreigner joining Hashem. I asked my Rabbi briefly about this passage. He explained that the passage is probably neither about a gerut conversion or someone becoming noachide, but something called a 'ger toshav'.

So, I'm asking if some one would like to enlighten me regarding this subject. I'm sorry I can't be more specific in my question, as this is a new concept to me.

Very grateful for any answers.

In light of @ba's comment (thanks, b a), I think this question should be reworded so it asks what a ger toshav is only, so people don't answer it with an explanation of Is., which is covered by the other question. Just MHO. – msh210 Sep 14 '12 at 5:30
@b a 4, thanks for the link – Ben Sep 14 '12 at 9:41
Rabbi David Katz from Tzfat Israel has done extensive research on the subject and has presented it in these two lessons. netiv.net/ger-101-rabbi-david-katz – user4599 Dec 6 '13 at 18:37

In Avodah Zarah 64b, they ask: Who is a "ger toshav"? Whoever accepts upon himself, in front of three friends, not to worship idolatry — these are the words of Rabbi Me'ir. And the rabbis say: Whoever accepts upon himself the seven sins which the sons of Noach accepted upon themselves. And others (i.e. Elisha Acher) say: None of these are a "ger toshav." A "ger toshav" is whoever accepts upon himself all the commandments except not to eat neveilah.

The Rambam (Isurei Biah 14:7) rules like the rabbis. This definition of a "ger toshav" is what we are regular to call a "ben Noach." So according to the halachah, there is no difference between a ger toshav and a ben Noach, but according to the other opinions in the gemara there is. The Rambam there says that he's called a "ger toshav" (lit. resident stranger) because he's allowed to live in Israel with us.

Thank you. Very interesting. – Ben Sep 14 '12 at 9:32
The difference between a ben Noach and a ger toshav would appear to be that the ger toshav accepts the designation and agrees to heed those seven commandments. – Monica Cellio Sep 14 '12 at 12:58
Note that I defined a ger toshav as "what we are regular to call a 'ben Noach'" (in reality, all of mankind are bnei Noach) – b a Sep 14 '12 at 20:19

Rabbi David Katz book The World of The Ger is an amazing resource for learning about Ger Toshav, it has help me in my search as a non-Jew on my path to honor Hashem..

Welcome to Mi Yodeya. Could you edit this to summarize what he says? We're looking for answers that stand alone, rather than just pointers to answers, so adding a little of what he says here will greatly improve this. Right now it seems more like a comment. Thanks! – Monica Cellio May 7 '15 at 12:50
