Among the speakers were Gov. Charlie Baker and Boston Mayor Marty Walsh.

“From the time that we started speaking here seven minutes ago, or eight minutes ago — there’s easily 500 more people here and they keep coming. People keep coming and the crowd keeps growing. So I want to thank you for that. We’re here today because we are letting the Jewish community know that we are standing with them here in Boston and around the world,” Walsh told the crowd.
