As we send today’s email, hundreds of people in Boston are searching for the missing 16-year old boy, Caleb Jacoby, son of the Boston Globe pro-Israel columnist Jeff Jacoby. Caleb has been missing since Monday in the coldest winter weather. We ask that you say a prayer (his Hebrew name is Calev Avraham ben Elisheva) or perform an act of loving kindness today in the merit of bringing home Caleb. For our northeastern U.S. readers, please be vigilant and keep a lookout for Caleb.
