Josef Schuster, the president of the Central Council of Jews in Germany, told Berlin public radio that Jews should exercise caution in big cities.
His comments come ahead of a "Berlin Wears Kippah" solidarity march in the German capital on Wednesday.
Last week, two young men wearing kippahs were assaulted in the city.
The attacker was filmed shouting anti-Semitic abuse.
Jewish organisations in Germany have expressed alarm over a number of recent anti-Semitic insults and threats in schools.
At the weekend, Chancellor Angela Merkel condemned what she described as "another form of anti-Semitism".
She told Israel's Channel 10 TV network that aside from anti-Semitism by right-wing groups, similar threats were coming from some Muslim refugees in the country.
Germany's Jewish population has grown rapidly since the fall of the Berlin Wall in 1989.
Before 1989, the population was below 30,000 but an influx of Jews, mainly from the former Soviet Union, has raised the number to more than 200,000.
This is so terrible that Jewish people have to suffer this sort of treatment in Germany of all places

You can still identify them by their dicks in Germany.

Hitler left many muslims as sleeper agents to destroy the jews, the jews never saw it coming.
Noah Morris
ikr, it's would be much better to have just killed them outright, that way there would be no suffering at all!

Yes, the suffering of the jewish people is terrrrible, it would be faaaaaantastic if we could all live in peace. The jews and the goyim in their proper stations of course. These 200,000 jews are the greatest victims of this teeeerrrible and unforeseen event, and the 100 million Germans should spend unlimited resources on making sure that jews can wear their special god hat that lets them receive signals from their Saturn-dwelling dark lots of chaos and misery. Two young men shouldn't be assaulted. It would be much better if it was some 12/13 year old German girls, who could be raped, tortured, murdered, dismembered and partially eaten by the enriching and diverse poor refugees, who are engineers and doctors fleeing the horrors of their own countries and just want a better life, creating their own special horrors in Germany and Europe instead. It isn't like all the jews haven't been constantly campaigning to import all of these subhumans, in order to destroy Europe. At least these poor, innocent jews can go to Israel after destroying Germany.

Keep in mind, we should focus on the 0.0002% of the population, and not the Germans themselves.

They dindu nuffin
Jace Hernandez
that's the best part, their government can't judge attackers, or ignore jew whining, so they can only blame white men of these attacks, good or the best timeline?
Lucas Fisher
If only they hadn't spent the last 80 years brainwashing the germans into being self hating cuckolds who want their country flooded with muslims. OOPS
Carson King
How long until a sand nigger vs kike race war breaks out?
The jews created about 30 bastardized dialects around the world. Goes to show people how clannish and racist they are to never learn the local language. Of course if confronted they instantly say, " 'cause sntisemitism." They would never admit the problem is their racist behaviour.
