The Open Siddur Project is a volunteer-driven collaboration between folk passionate about Jewish spiritual practice. Some are interested in the Siddur as a technology for preserving and disseminating an evolving history of Jewish ritual, practice, and sacred poetry. Others are energized by the design challenge of crafting Siddurim that function effectively for nurturing spiritual, emotional and creative intelligence. All of us see the potential that creative engagement holds for empowering students and teachers to take ownership of those ingredients comprising their shared cultural inheritance.

The Open Siddur is a non-prescriptive, non-denominational project whose only intent is to help revitalize Judaism by ensuring its collective spiritual resources — the creative content intended for communal use — remain free for creative reuse. The Open Siddur Project invites participation without prejudice towards ethnic heritage, skin color, nationality, belief or non-belief, sex, gender, sexuality or any other consideration. All we ask for is an intellectually honest commitment to the principles and sensibilities preserved in our mission statement.

the Rabbinical Assembly of America
The Rabbinical Assembly (RA) is the international association of Conservative rabbis. The RA was founded in 1901 to shape the ideology, programs, and practices of the Conservative movement. It publishes prayerbooks and books of Jewish interest, and oversees the work of the Committee on Jewish Law and Standards for the Conservative movement. It organizes conferences and coordinates the Joint Placement Commission of the Conservative movement. Members of the RA serve as rabbis, educators, community workers and military and hospital chaplains around the world. Rabbis ordained by Jewish Theological Seminary of America, the Ziegler School of Rabbinic Studies at the American Jewish University (California), The Seminario Rabínico Latinoamericano (Buenos Aires, Argentina), The Zacharias Frankel College (Berlin, Germany) and The Schechter Rabbinical Seminary (Jerusalem, Israel) automatically become members of the RA upon their ordination. Rabbis whose ordination is from other seminaries and yeshivas may also be admitted to the RA. As of 2010, there were 1,648 members of the RA. The majority of RA members serve in the United States and Canada, while more than ten percent of its rabbis serve in Israel and many of its rabbis serve in Latin America, in the countries of Europe, Australia, and Africa.

In July 1642 he left the Low Countries to go to Königsberg, where he spent the rest of his life until his death in 1652. He obtained a Hebrew manuscript of the Sefer Yezirah through the Mennonite merchant Gerebrand Anslo, for a translation into Latin in 1642 ( Liber Jezirah qui Abrahamo Patriarchae adscribitur). In 1644, he published his Latin translation of the Passover Haggadah. He made one of the earliest translations of Jewish prayers, under the title Hochfeyerliche Sollennitaeten, Gebethe und Collecten Anstatt der Opfer, Nebst Andern Ceremonien so von der Jüdischen Kirchen am Ersten Neuen-Jahrs-Tag Gebetet und Abgehandelt Werden Müssen, Königsberg, 1652. His posthumous work Bilibra Veritatis was written to substantiate the claim that the Targums prove the doctrine of the Trinity.
