According to Israel's President Shimon Peres, a fight is underway, for "the soul of the nation and the essence of the state." But the threat isn't coming from outside of Israel. It's over differing interpretations of Judaism.
Recently, a bespectacled eight year-old girl was filmed by a local TV station being harassed by ultra-Orthodox, or Haredi Jews, for, in their view, not dressing modestly enough. The episode took place in Beit Shemesh, a city between Tel Aviv and Jerusalem that has become a symbol of this growing battle in Israel.
In a protest that swelled into the thousands on Tuesday evening, demonstrators in Beit Shemesh rallied against what they say is the imposition of strict codes of religious behavior in communities across this country.
"It's enough, it's enough," says Dov Liptman. "It's reached a point where we have to stop it, and we are going to stop it."
Liptman belongs to the modern Orthodox sect of Judaism. While religiously observant, the modern Orthodox are not as strict as the ultra-Orthodox, or Haredim, who practice gender segregation. Also, many Haredi men devote their days to religious study and are not part of the workforce.
There are many different strands of Judaism, and the Haredim are one of the fastest growing populations in Israel. In Beit Shemesh, they make up about half of the residents.
Liptman says, as their numbers have grown they have been trying to force their values on the larger community.
"It's not an ultra-Orthodox city," he says. "It's a city for Jews, including ultra-Orthodox. We welcome them, but it's for all the populations."
Girls Complain Of Harassment
Most of the girls who study at an all girls' school on the edge of an ultra-Orthodox neighborhood say harassment is a regular occurrence.
"My sister and I walked down this street to school," says 15-year-old Yael. "I was wearing a long-sleeved shirt and a three-quarters length skirt, and they spat at us. They didn't like the way we were dressed. It happens all the time."
The Haredi also enforce gender segregation on public transport — women are required to sit at the back of the bus.
In Beit Shemesh, the ultra-Orthodox population has even sent out "modesty patrols" to enforce chaste female dress.
Yossi Shain, who heads the department of diplomacy at Tel Aviv University, says religious battles like this one will get worse as the Haredi population gets larger and their political clout grows.
"This is going to be exacerbated in the next few years because the demography is changing," Shain says. "The ultra-Orthodox have become, very much, I would say, intransigent, in some respects. It seems to be very powerful. It plays a very important role in the government and its leadership has become, much more, I would say, extreme in its views."
The ultra-Orthodox have two political parties that play a pivotal role in Israel's coalition politics. Critics say successive governments have given in to their demands and turned a blind eye to their excesses in the name of political expediency.
Israel has always sought to balance its democratic and Jewish identities, and secular Jews say recent developments have upset the balance.
"It is a battle for the soul of Israel," says Rabbi Shmuel Jakobowitz, an ultra-Orthodox leader.
He says people misunderstand the Haredim. They don't favor a kind of Jewish version of the Iranian theocracy that was ushered in with the Iranian Revolution three decades ago.
"People are understandably afraid of Khomeinism," Jakobowitz says, in a reference to Iran's revolutionary leader, Ayatollah Khomeini. "We as Haredi Jews are definitely not Khomeinist in our attitudes to the contemporary world."
He says that Haredi Jews should be allowed to live the way they wish.
"We find a lot of things abhorrent in the liberal way of living which is very permissive, which is very promiscuous, if I may use the word, which is very immodest to our mind. The dignity of women is protected much more with our method, with our system, than it is protected with the other system."
