Conversion, Part 1 Halakhic Attitude Toward Conversion & Converts

(33) When a stranger resides with you in your land, you shall not wrong him.

Rabbi Elazar said: The Holy One, Blessed be He, exiled Israel among the nations only so that converts would join them, as it is stated: “And I will sow her to Me in the land” (Hosea 2:25). Does a person sow a se’a of grain for any reason other than to bring in several kor of grain during the harvest? So too, the exile is to enable converts from the nations to join the Jewish people. And Rabbi Yoḥanan said that this idea may be derived from here: “And I will have compassion upon her that had not received compassion; and I will say to them that were not My people: You are My people” (Hosea 2:25). Even those who were initially “not My people,” i.e., gentiles, will convert and become part of the Jewish nation.

It is taught in a baraita that Rabbi Eliezer the Great says: For what reason did the Torah issue warnings in thirty-six places, and some say in forty-six places, with regard to causing any distress to a convert? It is due to the fact that a convert’s inclination is evil, i.e., he is prone to return to his previous way of living. What is the meaning of that which is written: “And you shall not mistreat a convert nor oppress him, because you were strangers in the land of Egypt” (Exodus 22:20)? We learned in a baraita that Rabbi Natan says: A defect that is in you, do not mention it in another. Since the Jewish people were themselves strangers, they are not in a position to demean a convert because he is a stranger in their midst.

Rabbi Ḥelbo says: Converts are difficult for the Jewish people like a leprous sore on the skin.
