New York City’s plague of anti-Semitism worsened Thursday, as yet another attack on a Jewish man in Brooklyn came to light and a woman in an earlier hate assault was hit with felony charges, police sources said.

The 13th incident in a holiday-season surge in violence against Jews was revealed when law enforcement sources said that three brutes accosted a 66-year-old Jewish man on Dec. 24 and said: “Jew, Hitler burned you, I’ll shoot you.”

The men fled after making the comment and didn’t touch the victim, but the incident at the intersection of South 4th and Keap streets in Williamsburg at 3.58 p.m. left him in fear, members of the Jewish community said.

Former state assemblyman and founder of Americans Against Anti-Semitism Dov Hikind said that the man had to be begged by family to report the incident.

“The son spoke to me. He convinced his father to go in and tell his story to police,” Hikind told The Post. “His father was so freaking terrified he didn’t want to go to police.”

Referring to the string of anti-Semitic incidents, Hikind said: “I’ve lost track. One goes into another.”

The troubling assaults in New York — the worst a savage machete attack during Hanukkah at a rabbi’s home in upstate ­Monsey on Saturday night — are now a nearly daily occurrence.

On Wednesday, two allegedly women yelled, “I will kill you Jews” while attacking a Hasidic man in South Williamsburg.

One of the women, Jasmine Lucas, 24, was arraigned on charges of second-degree robbery as a hate crime and second-degree assault and ordered held on $10,000 bond at an arraignment Thursday night. She pleaded not guilty. The second woman was not charged, police said.

On Tuesday, two more assailants threatened a Jewish teen at knife-point on a bus in Sheepshead Bay and took his yarmulke, law enforcement sources said.

The city experienced a 60% rise in anti-Semitic hate crimes in 2019 compared to 2018, the NYPD said.

Evan R. Bernstein, Anti-Defamation League New York and New Jersey regional director, said the one question he kept repeatedly hearing was, “Why?”

“There’s no solid answer,” Bernstein said. “It’s frustrating.

“We need to get information from perpetrators by asking them, ‘Why did you hit this person? Was it a prank? It is because you’re mentally ill? Was it because you were drunk? Or was it because your parents told you to hate Jews?’ Right now we don’t know, and that’s the problem.”

Bernstein praised the actions of Gov. Andrew Cuomo, who on Wednesday announced he had directed State Police to boost their patrols in Orthodox communities.

But he criticized comments made by Mayor Bill de Blasio in June when he said the violence was a “right-wing movement.”

“This has nothing to do with white supremacy,” Bernstein said. “This is anti-Semitism.”

“There’s been a normalization of anti-Semitism in New York City over the last six years and that’s something I never thought I’d see.”
