The shooting in California happened on the last day of Passover, while many were focused on celebrating the holiday, adding to the pain and anger.
Prayers and words of support – all part of an all-too-familiar process.
"We're with you, we stand with you," said Massachusetts Governor Charlie Baker.
"Here we are again," said Marc Baker, president of the Combined Jewish Philanthropies. "Any time would have been too soon, too frequent, we are saddened, we are shaken."
The local Jewish community gathered at the Holocaust Memorial in Boston to speak out against the deadly shooting in California at the Chabad of Poway on the last day of Passover.
"Their holiday was brutally disrupted by the anti-Semitic shooting attack fueled by hate and darkness," said Hirsch Zarchy, a rabbi and the founding director of Harvard Chabad.
Just six months ago, many of the same community members gathered to mourn after the mass shooting at the Tree of Life Synagogue in Pittsburgh.

Although they say they refuse to give into fear of hateful acts of violence, they are also focused on security.
"I think that one of the things that we find is that people want to balance having a warm and welcoming communities with making sure that their synagogues are safe and secure," Marc Baker said.
The Combined Jewish Philanthropies works with local synagogues and Chabads to help them with best practices in case of an attack. Governor Charlie Baker says the state’s hate crime task force is working with federal agencies to prevent them.
"I simply can't imagine what it must be like to get up in the morning and discover that someone has been shot, killed or injured in a house of worship simply because they share the same religion," said Governor Baker.
They're hoping to match that hate with resilience.

"I feel enraged and saddened and terrible about this, but I only feel stronger," said Leo Kugryavtsav of Newton.
On Monday night, another vigil was held at Beth Menachem Chabad of Newton in honor of the 60-year-old woman killed and three others wounded.
"We're with you, we feel your pain, we're grieving with you, we're going to be strong, we won't be afraid," said Rabbi Shalom Ber Prus.
Newton's mayor and Middlesex DA Marian Ryan were in attendance Monday.
The rabbi tells Boston 25 News the congregation is constantly meeting with security experts and law enforcement to develop safety plans.
Baker revived the hate crime task force in 2017 after a rise in anti-Semitic incidents across New England.
