This coming Sunday's Jewish Heritage Day at Citi Field, presented by the Mets and the JCRC, is always a terrific day at the ballpark, and the Mets deserve our gratitude. Last winter, the Hebron Fund rented out a room at Citi Field for a fundraiser on behalf of one of Israel's oldest and holiest communities, a community that has lived in Hebron almost continuously since Biblical times, until wiped out in the Arab pogrom of 1929 and reconstituted shortly after the Six-Day War in 1967.
