Musar su Osea 2:25

Rabbi Eleazar tells us in Pesachim 87b that G–d sent Israel into exile among the nations so that we could proselytize members of our host countries since it says in Hoseah 2,25: וזרעתיה לי בארץ, "I will plant it (Israel) all over the earth for My sake." A person does not use a bushel of seed when he plants his field unless he hopes to get many times that amount in return. Placing Jews in exile was like seeding the nations of the world. G–d expects a substantial harvest of people who will embrace monotheism through contact with Jews. Rabbi Yochanan uses the second half of this verse to arrive at the same conclusion, i.e. ורחמתי את לא רוחמה, ואמרתי ללא עמי, עמי אתה והוא יאמר אלוקי, "I will have mercy with the one that was out of favor, and I will say to the one who was not My people "My people," and it will respond by saying "my G–d." Rashi comments that these are the converts that cleave to the Jewish people. Israel's dispersion therefore had the same purpose as Adam's expulsion from Paradise. More people will return to the Holy Land after the arrival of the Messiah than had ever been dispersed, since it will include those who have converted to Judaism in the interval.

Now that our exile has lasted so long because of our many sins it is more important than ever that Israel should separate themselves from the vain things of the world and take hold of the Seal of the Holy One, Blessed be He, which is Truth — and sanctify themselves even in things that are permitted to them (Yebamoth 20a), and not to lie — not to a Jew and not to a heathen, and not to deceive them in any matter, as it is said, "The remnant of Israel shall not do iniquity, nor speak lies, neither shall a deceitful tongue be found in their mouth" (Zeph. 3:13). And it is further written, "And I will sow her unto Me in the land" (Hos. 2:25). Surely a man sows a seah in order to harvest many kurim, thus, the Holy One, Blessed be He, exiled Israel among the nations only so that proselytes might join them (Pesahim 87b). And so long as they conduct themselves among the heathens without guile, the latter will cleave to them. And behold the Holy One, Blessed be He, was furious with the wicked for their robbery, as it is said, "For the earth is filled with violence" (Gen. 6:11).
