An anonymous donor gave the funds for the mammoth event being held in Tel Aviv's Rabin Square Sunday night, calling for the safe return of the three abducted yeshiva boys – Gilad Sha'ar, Naftali Frenkel and Eyal Yifrah.

Speaking to Arutz Sheva, Rachel Frenkel - whose son Naftali (16) was abducted by terrorists together with Gilad Sha'ar (16) and Eyal Yifrah (19) - said it was "overwhelming" to know that Israelis of all backgrounds had joined the event in a show of love and support for the families.

Asked how she felt about the government's efforts so far to free her boys she said "they're doing everything we expect."

Watch: Rachel Frenkel speaks to Arutz Sheva:

Marc Belzberg, founder of the One Family organization for assisting terror victims, told Arutz Sheva that the families of the missing teens asked for an event that would create unity among Israelis and would involve “the entire nation of Israel praying together.”

The event saw secular and religious artists performing on stage and was aired on television newscasts.

Belzberg recalled that One Family was founded after his daughter had to cancel her Bat Mitzva party because of the Sbarro terror bombing, which took place hours before the planned event, on August 9, 2001. His daughter decided to take the money that was supposed to go into the celebration, and use it instead for assisting victims of the attack.

The effort turned into a long term family project, which has assisted more than 3,000 terror victims since then.

The organization has mapped out five districts that cover the entire state of Israel , with a coordinator assigned to each district, whose job it is to visit terror victims' families and offer them assistance even before they ask for it.

While the National Insurance Institute also provides assistance to terror victims' families, explained Belzberg, One Family's activities are not limited to office hours and involve more emotional closeness.

Earlier today, the parents of the abducted Israeli teenagers went for the first time to visit the hitchhiking post their sons were last spotted at near the town of Alon Shvut, in the Gush Etzion region south of Jerusalem.

While there the parents took the opportunity to thank some of the soldiers who have been working night and day to find their boys, as part of the IDF's Operation Brother's Keeper. Gush Etzion is located just north of Hevron, where a massive search operation is ongoing for the missing teens, who are believed to be held there by Hamas terrorists.
