In the latter parts of the Book of Deuteronomy, when Moses' death was near, he prophesied about the destiny of the people of Israel. Their destiny would not be promising – curses would come upon them and they would go into exile – but when they return to their homeland later, their situation will be as good as it had been in the past, and so said Moses: In the process of the gathering of the exiles of Israel Moses emphasizes the followings points:
Following conditions attached to: "and you will return to the Lord, your God."
The exiles "at the end of the heavens" will also return.
The situation will be improved after the ingathering of the exiles of Israel in the land of Israel: "and He will do good to you, and He will make you more numerous than your forefathers."
Prophets' promise
The Nevi'im prophesying after the destruction of the First Temple had encouraged the Babylonian exiles by reiterating the words of Moses. In chapter 11 the Book of Isaiah says: In chapter 29 the Book of Jeremiah says: In chapter 20 the Book of Ezekiel says:
Benediction regarding Kibbutz Galuyot
The Jewish rabbinical sages, Chazal, included the "Benediction Regarding Kibbutz Galuyot" among the thirteen benedictions of appeal in the Amidah, the central prayer of the Jewish liturgy. It is the earliest benediction wherein an appeal is made concerning subjects relating to Jewish nationality and restoring the existence of the Hebrew nation as an independent nation, the others being Birkat HaDin, Bo'neh Yerushalayim, and Birkat David.
Maimonides
In Law of Kings, Maimonides writes: According to Maimonides, of all the assignments attributed to the messiah, the Torah attested to one: "then, the Lord, your God, will bring back your exiles", the ingathering of the exiles of Israel, a Kibbutz Galuyot. The messiah is the ingatherer of the exiles of Israel.
Other Jewish scholars
Other Jewish scholars view this differently from Maimonides. They argue that the Torah attested to a period, not a person, the period in which the People of Israel return to their homeland, the land of Israel. The act of ingathering of the exiles of Israel in the land of Israel, a Kibbutz Galuyot, will bring about the coming of the messiah, as the hand of God is in the events of the creation of the State of Israel, obviously a different reality then Maimonides depicts, though they see the writings of Maimonides as a way of learning the importance of the role of the messiah, since the Maimonides was a scholar not a prophet, and did not live up to see the event of the establishment of the State of Israel. Zvi Yehuda Kook, one of the leaders of the Religious Zionist Movement, used to quote from the Responsa book, Yeshuot Malko, of Israel Yehosha of kutna, in conjunction with Aliyah : "There is no doubt that this is a greater Mitzvah, because the gathering is an Atchalta De'Geulah , as attested, "I will yet gather others to him, together with his gathered ones", and see Yebamoth, page 64, "the Divine Presence does not rest on less than two myriads of Israelites", especially nowadays in which we have seen the great desire inasmuch as in men of lesser importance, mediocre ones, and upright in heart, it is more than likely that we would gleam with the spirit of salvation, fortunate are the "ones who" take part in "bringing merit unto the masses" Haredi Judaism and Chabad movement takes the writings of the Maimonides literally: The messiah is assigned to mission of completing the ingathering the exiles of Israel. Until then, the Jewish community living in Israel is defined as a Diaspora of Israel, though they give their consent to the Jewish rule of Israel, and see the advantages of it.
Terms of Jewish nationality
1. Cyrus's Declaration, Ezra 1:3 2. Napoleon, in his Proclamation to the Jews of Asia and Africa, implicitly suggested rebuilding the Holy Temple in Jerusalem, which had been destroyed for the second time: The French scholar Henry Laurens holds that the proclamation never took place and that the document supposedly proving its existence is a forgery. 3. Balfour Declaration of 1917:
The intensive involvement of the Zionist Movement ever since in transporting Jewish legal and nonlegal immigrants to the land of Israel, attests to the importance they've attributed to that goal. Aliyah Bet is the illegal entrance to the land of Israel under the British Mandate's laws, including during World War II and the Holocaust. Aliyah Bet was organized by the Yishuv from 1934 until the State of Israel began in 1948. Aliyah Bet was carried out by the Mossad Le'aliyah Bet, a branch of the Jewish Defense Association, the para-military organization that was to become the Israeli Defense Force. During Aliyah Bet 's 14 years of activity, 115,000 Jews made Aliyah to the land of Israel. The term Aliyah Bet is composed of the Hebrew word Aliyah, meaning Jewish Immigration to the land of Israel, and the Hebrew Letter Bet, the second letter in the Hebrew Alphabet. Its use was analogous to the English term "Plan B". Vis-a-vis, the illegal transportation of immigrants was being carried out simultaneously with the legal Jewish immigration to the land of Israel permitted by the British Mandate. The Mandate attempted to limit the number of immigration certificates in a way which contradicted the national goals of the Jewish community living there. Aliyah Bet started only modestly in the midst of the nineteen-thirties. The majority of Jewish immigrants, the Olim, arrived after World War II and the Holocaust. Aliyah Bet was carried out in various methods:
The Law of Return, a law passed in 1950 in memory of the Holocaust, allows every Jew the right to make Aliyah to the State of Israel and to receive a certificate of Aliyah, which grants the certificate holder an Israeli Citizenship immediately. This stems from Israel's identity as the Jewish State, which is connected to the idea of the gathering of Israel.
Yom HaAliyah is a new Israeli national holiday officially passed into law on June 21, 2016. Yom HaAliyah is to be celebrated annually on the tenth of the Hebrew month of Nisan. The day was established to acknowledge Aliyah, immigration to the Jewish state, as a core value of the State of Israel, and honor the ongoing contributions of Olim to Israeli society.
