From a Wall Street Journal story by Joanna Stern headlined “When Our Smartphones Become Windows to a War”:

Ha kol b’seder. In Hebrew it means, “Everything is OK.”

That’s what 22-year-old Inbar Shem Tov whispered in a video sent to her father while hiding in a dumpster from Hamas attackers. Around her you can see other young women, clinging to their phones, sending WhatsApp messages.

That video was one of the last things she would send before she was killed.

Anne Frank had a diary to document the fear she experienced hiding from Nazis. Inbar Shem Tov had a smartphone.
