Oz Lelohim, including the work Meheimnuta DeKalah, with commentaries Oz LElohim and Beit Kodesh HaKodashim by Sabbatean Nechemiah Chiya Hayyun. Berlin: Baruch Buchbinder, [1713]. "Amsterdam" emphasized on title page. Only edition.

Original decorated wood and leather binding, with clasp.

While Hayyun presented Meheimnuta DeKalah as an ancient kabbalistic work, it was in fact the Raza DiMeheimnuta delivered by Shabtai Tzvi, as identified by R. Yosef Ergas.

The approbation Hayyun received from R. David Oppenheim for his Divrei Nechemiah commentary on the Torah was reused for the present book without his permission, along with an approbation he had received from R. Naftali Katz. Both later retracted their approbations, but Hayyun refused to return them; they both published their retraction in Milchamah LaShem Cherev LaShem by R. Moshe Chagiz (Amsterdam, 1714).

Nechemiah Chiya Hayyun (ca. 1655-1730) was a Sabbatean Torah scholar and kabbalist, the most prominent Sabbatean after the death of Shabtai Tzvi. When Hayyun's books were brought to the Chacham Tzvi during his tenure as Rabbi of Amsterdam, he found them to contain heretical and Sabbatean material and issued a ban against them and their author, and began a fierce battle against him. The Chacham Tzvi was joined by R. Moshe Chagiz in his battle against Hayyun, and both suffered the persecution of Hayyun's supporters in Amsterdam. Hayyun extracted the approbations to his book by fraud and deceit.
