A remarkable new demographic says that Jews of color make up 10-20% of the Jewish population. When we look around our congregations, it may be hard to believe that statistic. There are many who are not counted because we’re not doing a good job of opening our arms wide.  Like our ancestors, we focus on our own modern day tribes: The tribes of the Reform, Conservative, Orthodox, Reconstructionist, and secular. Amidst our real differences, can we sew ourselves together into a larger identity of being Am Yisrael – one people?  Rabbi Rick Jacobs, president of the Union for Reform Judaism, discusses these themes in this week's Torah portion, Parashat B'midbar.
