The donation of blood for the saving of lives is a mitzvah of Piku’ach Nefesh. To donate, just come to the synagogue’s social hall anytime between 10:00 am and 2:00 pm on Wednesday December 24. You can either drop in. Or to save wait time, schedule an appointment by calling 1-800-RED CROSS (1-800-733-2767) or visiting www.redcross.org
