Rabbi Eitan Webb, when I come to interview him early last Wednesday in his Nassau Street apartment, is juggling with ease five things at once. The sun rages to highlight red flourishes in his beard and the car beeps become louder as the Princeton Borough awakens, but he is preparing to have some thirty students over for Passover seder, arranging to have a Matzah Ball party with a middle weight boxing champion, balancing his son on his lap, updating the Chabad website, and fingering an official letter from President Shirley Tilghman.
