Jewish wisdom says a child's Torah education should start with the Book of Leviticus. As we read its second portion, Parashat Tzav, we share an episode that first ran in 2018, just after a school shooting in Parkland, FL, killed 17 people and injured 17 more. Rabbi Rick Jacobs stresses the importance of fighting for and with our young people, raising up the Jewish teens who, amid tragedy, mobilized for gun violence prevention.
