“The blessed Holy One scattered Israel among the peoples only so that they may accumulate converts, for it is said: And I will sow her for Myself in the earth; [and I will have mercy upon her that had not obtained mercy; and I will say to them who were not My people, you are My people; and they shall say, You are my God] (Hosea 2:25)—surely, a man sows a se’ah in order to harvest many korin….
Rabbi Yoḥanan said: The ingathering of the exiles is as important as the day when the heavens and the earth were created, for it is said, Then shall the children of Judah and the children of Israel be gathered together, and appoint themselves רֹאשׁ אֶחָד (rosh eḥad), one head, and they shall come up out of the land: for great shall be the day of Jezreel (Hosea 2:2); and it is written, And it was evening and it was morning, יוֹם אֶחָד (yom eḥad), first day (Genesis 1:5)” (BT Pesaḥim 87b–88a, cf. Zohar 1:244a).
“‘The ten tribes will not return, as is written, And flung them into another land as on this day (Deuteronomy 29:27)—just as the day goes and does not return, so they too went and will not return: the words of Rabbi Akiva. Rabbi Eli’ezer said: As on this day—just as the day darkens and then becomes light again, so the Ten Tribes. Even as it went dark for them, so will it become light for them’ (M Sanhedrin 10:3).
Our Rabbis taught: The ten tribes have no portion in the World to Come, as it says, And YHWH tore them from upon their soil in wrath and in anger and in great fury [and flung them into another land as on this day] (ibid.). And YHWH tore them from upon their soil—this world; and flung them into another land—the World to Come: the words of Rabbi Akiva. Rabbi Shim’on son of Yehudah, of the village of Akko, said in the name of Rabbi Shim’on: If their deeds are as this day’s [i.e., if they do not repent, this day referring to the time of their being exiled], they will not return; otherwise they shall. Rabbi said: They will enter the future world, as is said, [And it shall come to pass] on that day, that the great shofar shall be blown, [and they shall come who were ready to perish in the land of Assyria, and the outcasts in the land of Egypt, and shall worship YHWH in the holy mount at Jerusalem] (Isaiah 27:13).
Rabbah son of Son of Ḥanah said in Rabbi Yoḥanan’s name: [Here] Rabbi Akiva abandoned His חֲסִידוּת (ḥasidut), kindness, as is written, Go and proclaim these words toward the north, and say, Return, you backsliding Israel, says YHWH; and I will not cause My anger to fall upon you: for I am חָסִיד (ḥasid), kind, says YHWH, and I will not keep anger forever (Jeremiah 3:12).
Now, to what does ‘his kindness’ refer? As has been taught: The children of the wicked of Israel, [who died] in their minority, will not enter the future world, as is written, For, behold, the day comes, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that comes shall burn them up, says YHWH of Armies, that it shall leave them neither root nor branch (Malachi 3:19). [… It shall leave them neither] root—this world; [nor] branch—the World to Come: the words of Rabban Gamaliel.
Rabbi Akiva said: They will enter the World to Come, as is written, YHWH protects פְּתָאיִם (peta’im), the simple (Psalms 116:6), and in the island cities, a child is called פָּתִּיאָ (pattia); and it is said also, Cut down the tree and destroy it but leave one of its roots in the ground (Daniel 4:20). How then do I fulfil that it shall leave them neither root nor branch? That He shall not leave them [unpunished the violation of] a single mitsvah nor the remnant of a mitsvah [i.e., even the most insignificant mitsvah]. Another interpretation: root—the נְשָׁמָה (neshamah), soul; branch—the body [but of the wicked themselves, not their children. Thus we see Rabbi Akiva, in his love for Israel, interpreting the verse as leniently as possible]. But as for young children of the wicked gentiles, all agree that they will not enter the future world. And he derives it from [They are dead, they shall not live; they are deceased, they shall not rise: therefore have] You visited and destroyed them, and made all their memory to perish (Isaiah 26:14)” (BT Sanhedrin 110b, cf. Sifra, Be-Ḥukkotai, 8:1).
And it shall come to pass in that day, that YHWH shall set His hand again the second time to recover the remnant of His people, who shall be left, from Assyria, and from Egypt, and from Pathros, and from Cush, and from Elam, and from Shinar, and from Hamath, and from the coastlands of the sea. And He shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth (Isaiah 11:11–12).
“And Israel saw Joseph’s sons and he said, ‘Who are these?’ (Genesis 48:8).
Rabbi Abba opened, ‘It is said: Then shall you say in your heart, who has begotten for me these, [since I have lost my children, and am desolate, a captive, and moving to and fro? and who has brought up these? Behold, I was left alone; these, where had they been?] (Isaiah 49:21). What does this mean? Israel below [i.e., on earth] saw that the children of Israel will come before Him, when they will come from Elam, and from Shinar, and from Hamath, and from the coastlands of the sea (Isaiah 11:11), and a vast flock will be established. The Shekhinah will say, Who are all these? Are there not any who are unfit, of foreign children? They will say to Him, We are all Your children, there is no foreigner among us! For they will be severed the one from the other [i.e., the motley throng will be severed from the Assembly of Israel]. And they will be circumcised together and converted. The convert then will return together with Israel and they will be as one.
It was taught: ‘[Rabbi Ḥelbo said:] Converts are as tough for Israel as a סַּפַּחַת (sapaḥat), scab’ (BT Qiddushin 70b; Yevamot 47b; Niddah 13b; Zohar 3:206b), as is written, For YHWH will have compassion for Jacob, and will yet choose Israel, and set them in their own land: and the strangers shall be joined with them, וְנִסְפְּחוּ (ve-nispeḥu), and they shall cling, to the house of Jacob (Isaiah 14:1). When the children will return to their land and there will be compassion among them, then YHWH will be one and His name one (Zechariah 14:9). Then the convert will tag along with the people of Israel like a scab on their skin.’
Why? Come and hear: Rabbi Shim’on said it refers to the borders of the land, for every one will want to live in the land of Israel, and the inhabitants will be afraid. It is written, [Enlarge the place of your tent,] and let them stretch forth the curtains of your habitations: [spare not, lengthen your cords, and strengthen your stakes] (Isaiah 54:2). The curtains you once had, should be stretched and strengthened, as it were, more than those of the other peoples whom you saw strengthening them in your exile. [Indeed, a vast flock of converts] will be established” (Zohar 1:215a).
“Yehudah, an Ammonite convert, came before [the Rabbis] in the academy. He said to them: How can I enter the assembly [i.e., marry a Jewish woman]? Rabbi Yehoshu’a said to him: You are permitted to enter the assembly. Rabban Gamaliel said to him: Has it not already been said, No Ammonite nor Moabite shall come into YHWH’s assembly. [Even his tenth generation shall not come into YHWH’s assembly ever. Because they did not greet you with bread and water on the way when you came out of Egypt, and for their hiring against you Balaam son of Beor from Aram Naharaim to curse you] (Deuteronomy 23:4–5)? Rabbi Yehoshu’a replied to him: Do Ammon and Moab still reside in their [original] place? Sennacherib king of Assyria long ago went up and בַּלבֵּל (balbel), baffled, all the nations, as it says, [For He says, By the strength of My hand I have done it, and by My wisdom; for I am prudent: and] I have removed the borders of the people, and have robbed their treasures, and I have put down the inhabitants like a valiant man (Isaiah 10:13); and whatever separates, separates from the greater part [and the assumption is that he is from the majority of nations whose members are permitted to enter the assembly, cf. BT Ketubbot 15a in the name of Rabbi Zeira]. Rabban Gamaliel said to him: But has it not been said: And afterward I will bring again the captivity of the children of Ammon, says YHWH (Jeremiah 49:6) so that they have already returned? Rabbi Yehoshu’a replied: And has it not been said, And I will bring again the captivity of My people of Israel, [and they shall rebuild the waste cities, and inhabit them; and they shall plant vineyards, and drink their wine; they shall also make gardens, and eat the fruit of them] (Amos 9:14), and they have not yet returned? Immediately they permitted him to enter the assembly” (BT Berakhot 28a).
“In that day shall Israel be the third with Egypt and with Assyria, a blessing in the midst of the land [whom YHWH of armies shall bless, saying, Blessed be My people Egypt, My handiwork Assyria, and My heritage Israel] (Isaiah 19:24).
The seventy princes who govern the army on high are divided in their midst. One division is governed by the prince of Ishmael, called Egypt, and the other division is governed by the prince of Edom, called Assyria [cf. 2 Kings 16; Isaiah 7–9; 2 Chronicles 28]. Both divisions receive from Gevurah, at the left side of the Chariot, but as we said, Gevurah is divided in two: one aspect is harsh judgment and the other weak [cf. Zohar 2:178a, 187a]; the harsh is exceedingly hard and the weak is soft. However, one stately light expands from the way of Tif’eret engulfing these two qualities, covering and influencing them. And in the future yet to come, when these two princes behold this light, they will call it the Light of Blessing, as is written, In that day shall Israel be the third with Egypt and with Assyria, a blessing in the midst of the land. And look, truly some of the nations will be restored to the dominion of Israel” (Berit Menuḥa, Third Way: The Way of Peace, cf. Zohar 1:13a, 164a; 2:57b; 3:218a–b [RM], 227b).
And strangers will stand and feed your flocks; foreigners will be your plowmen and your vinedressers. But you shall be named the Priests of YHWH: men shall call you the Ministers of our God: you shall eat the riches of the gentiles, and in their glory shall you boast yourselves (Isaiah 61:5–6, cf. Mekhilta, Shabbeta, Ki Tissa 1; BT Berakhot 35b; Zohar 1:143b).
“Rabbi Ḥiyya was traveling to visit Rabbi El’azar. He found him sitting next to Rabbi Shim’on son of Rabbi Yose, son of Lekonya, his father-in-law. As he raised his head, he saw Rabbi Ḥiyya. He said, ‘In that day shall Israel be the third with Egypt and with Assyria, a blessing in the midst of the land, whom YHWH of armies shall bless, saying, Blessed be My people Egypt, My handiwork Assyria, and My heritage Israel’ (Isaiah 19:24). How foolish are the inhabitants of the world, who do not know or consider the words of Torah!
Are then Ashur and Egypt close to the blessed Holy One? Rather, all those members of the exiles who will go up from Egypt and Ashur. But if we say that it is Egypt and Ashur [themselves] it refers to the pious among them who repent, and remain to serve Israel and King Messiah, as is written, and may all kings bow to him, and all nations serve him (Psalms 72:11), and, kings shall be your foster fathers [and their queens your nursing mothers: they shall bow down to you with their face toward the earth, and lick up the dust of your feet; and you shall know that I am YHWH: for they shall not be ashamed that wait for Me] (Isaiah 49:23) [cf. BT Shevu’ot 47b: ‘In the academy of Rabbi Yishma’el it was taught: The servant of a king is like a king’]” (Zohar 2:57b).
“All things will be fittingly restored, and the impure aspect will be eliminated from the world. This has been affirmed, as is written: I will eliminate the spirit of impurity from earth (Isaiah 25:8). The blessed Holy One will then remain alone, as is written: Idols will utterly vanish (ibid. 2:18), and similarly: YHWH alone will be exalted on that day (ibid., 17)—He alone, as is written: No alien god with Him (Deuteronomy 32:12), for it will be eradicated from the world. Nothing will remain above or below except the blessed Holy One alone and Israel serving Him, a holy people—called ‘holy,’ as is written: Whoever is left in Zion, who remains in Jerusalem, will be called holy (Isaiah 4:3). Then there will be a single world above and below—a single above; a single world below, a single people serving Him, as is written: Who is like Your people Israel, a single nation on earth? (1 Chronicles 17:21) [Rabbi Moshe Cordovero maintains that other nations will be purified and integrated into Israel, see Or Yaqar]” (Zohar 1:164a).
