JERUSALEM (JTA) — Jerusalem will host a challah bake as part of the world-wide Shabbos Project.

Hundreds of Jerusalem women and girls are expected to take part Thursday evening in the Great Big Jerusalem Challah Bake, hosted by celebrity chef and author Jamie Geller.

Events for The Shabbos Project are scheduled to take place this weekend in 170 cities around the world. The project originated in South Africa as an initiative of the country’s chief rabbi, and calls on Jews to keep the upcoming Sabbath together.

“Preparing the challah for Shabbat is known to be a time of reflection and devotion to the Jewish faith and tradition,” Geller said. “What an amazing experience this will be together with hundreds of other women from all backgrounds, coming together to perform this mitzvah.”

Additional Shabbos Project events scheduled for Oct. 24-25 include joint communal meals and festive havdalah ceremonies and concerts.
