The Birthright-Taglit program are to receive a much-needed infusion of cash from top philanthropists Sheldon and Dr. Miriam Adelson.

The Jewish-American couple has donated $13 million to the program’s coffers, it was announced, adding to the $20 million they gave earlier this year.

As a result, an additional 5,000 young Jewish  adults will be able to visit  Israel expense free, and become acquainted with their heritage.

The program, founded in 2000, has brought more than 300,000 young adults to Israel, from 59 different countries.

The Adelsons are known for their generosity to Jewish causes, particularly in Israel. The couple gifted some $25 million to the Yad Vashem Holocaust Memorial Museum Center last year.

Sheldon Adelson’s assets were estimated in 2012 by Forbes Magazine at $24.9 billion.

In a news release issued Tuesday, the 78-year-old hotel and casino owner called the program “the best vehicle to strengthen the Jewish community and our People’s connection with the State of Israel.”

Miriam Adelson said in the release that she and her husband felt “blessed that we have been able to contribute to the growth of this remarkable program,” and called on others – including the Jewish Federation – to increase their own support.
