Dear Rabbi, Why is blue the color of Judaism/Israel? I have combed the Torah for clues, but can find nothing that touches the subject. Was the choice of color set by long tradition or ordained by God? If by God, where in scripture does the prescription appear? If by long tradition, what are its origins and history? thank-you for your help.

How can I learn about the preserved sabbatical seven year cycle and how it starts and ends in relation to the calendar and the fall feasts. Thank you

I would like to know if you can refer someone who I may talk regarding medical issues considering a resident on call on Shabbos and Yom Tov. I live in Brooklyn, NY. Thank you.

My question is on the last day of pesach, should you lite a yarziet candle for the passing of my father of January, 2005?

Dear Rabbi, Why is blue the color of Judaism/Israel? I have combed the Torah for clues, but can find nothing that touches the subject. Was the choice of color set by long tradition or ordained by God? If by God, where in scripture does the prescription appear? If by long tradition, what are its origins and history? thank-you for your help.
