There was a great court at Jerusalem called Beth Yaazek, where all witnesses (who could testify to the time of the appearance of the new moon) used to assemble, and where they were examined by the authorities. Grand feasts were prepared for them as an inducement to them to come (and give in their testimony). Formerly they did not move from the place they happened to be in when overtaken by the Sabbath, but Rabbon Gamliel the elder ordained that they might in that case move two thousand cubits either way.
