Gáza

It is a land which your God יהוה looks after, on which your God יהוה always keeps an eye, from year’s beginning to year’s end.

Rabbi Elazar said that Rabbi Ḥanina said: Torah scholars increase peace in the world, as it is said: “And all your children [banayikh] shall be taught of the Lord, and great shall be the peace of your children” (Isaiah 54:13). If all the children of Israel are taught of the Lord, there will be peace for all.

The Gemara relates that the tanna who recited mishnayot and baraitot in the study hall taught a baraitabefore Rav Naḥman bar Yitzḥak: Anyone who humiliates another in public, it is as though he were spilling blood. Rav Naḥman bar Yitzḥak said to him: You have spoken well, as we see that after the humiliated person blushes, the red leaves his face and pallor comes in its place, which is tantamount to spilling his blood. Abaye said to Rav Dimi: In the West, i.e., Eretz Yisrael, with regard to what mitzva are they particularly vigilant? Rav Dimi said to him: They are vigilant in refraining from humiliating others, as Rabbi Ḥanina says: Everyone descends to Gehenna except for three.

In the towns of the latter peoples, however, which your God יהוה is giving you as a heritage, you shall not let a soul remain alive.

All the above matters apply only in an era when Israel is in exile among the idolaters or in an era when the idolaters are in power. When, however, Israel is in power over them, it is forbidden for us to allow an idolater among us.
Even a temporary resident or a merchant who travels from place to place should not be allowed to pass through our land until he accepts the seven universal laws commanded to Noah and his descendants, as [Exodus 23:33] states: "They shall not dwell in your land" - i.e., even temporarily.
A person who accepts these seven mitzvot is a ger toshav. A ger toshav may be accepted only in the era when the [laws of the] Jubilee Year are observed. In an era when the [laws of the] Jubilee Year are not observed, however, we may accept only full converts [to Judaism].

§ The Gemara relates: There was a certain slave who fled from his master from outside of Eretz Yisrael to Eretz Yisrael. His master followed him to Eretz Yisrael and came before Rabbi Ami. Rabbi Ami said to the master: We will write a promissory note for his value for you, and you should write a bill of manumission for him. And if you do not do this, I will remove him from you entirely, since he does not have to return to outside of Eretz Yisrael, based on the statement of Rabbi Aḥai, son of Rabbi Yoshiya.
