With the workmen finished construction and most of the interior finished, Congregation Beth Israel takes an important first step this Friday, holding its first Shabbat services in its new building. Although the Aron Hakodesh (holy ark) has yet to be finished, two of the congregation’s sefer Torah scrolls will be housed in a temporary ark loaned by neighbor Congregation Gates of Prayer. The permanent wooden ark, which is being shipped from Israel, will be installed in July by the artist whose plans were selected by a subcommittee of the congregation charged with that task. He will travel from Israel and oversee its placement in the new sanctuary. Plans for the official dedication weekend August 23-26 have been announced including special guest speakers Rabbi Avi Weiss of Yeshivat Chovevei Torah rabbinical school and Rabbi Tzvi Hersh Weinreb of the Orthodox Union .
