Last Thursday, a Biblical commandment that hasn’t been seen in 2,000 years was fulfilled. In the Cardo neighborhood of the Old City of Jerusalem, two witnesses stood before the Sanhedrin and gave testimony that established the beginning of the new month.Setting the new month by witnesses is considered by Rashi, a prominent commentator on the Bible, to be the first mitzvah (Biblical commandment) the Nation of Israel received after leaving Egypt. With great spiritual meaning, establishing the calendar is far more than a convenience. It is so important that it takes precedence over the Sabbath. In Biblical times, witnesses were permitted to break the Sabbath in order to arrive in Jerusalem and stand before the Sanhedrin.
