If any of thine be driven out unto the outmost parts of heaven, from thence will the Lord thy God gather thee, and from thence will he fetch thee:
And the Lord thy God will bring thee into the land which thy fathers possessed, and thou shalt possess it; and he will do thee good, and multiply thee above thy fathers. Deuteronomy 30:3-5
On July 5, 1950, the Israeli Knesset passed the Law of Return:
The Law of Return 5710 (1950)*The law has been amended twice (1954 and 1970), and has served as a step in the fulfillment of the prophecy in Deuteronomy 30.

2. (a) Aliyah shall be by oleh's visa.
(b) An oleh's visa shall be granted to every Jew who has expressed his desire to settle in Israel, unless the Minister of Immigration is satisfied that the applicant
