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 12 pm and 5:00 pm on Thursday August 20. 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
