ISAAC BEN ABRAHAM OF NEUSTADT:
Dutch cabalist; lived at Amsterdam in the seventeenth and eighteenth centuries. He was an assistant rabbi at Amsterdam, where he devoted himself to the editing of cabalistic works. In 1701 he published, from a manuscript he had in his possession, the "Sefer Raziel ha-Gadol" of Eleazar of Worms, in the preface to which Isaac expresses his firm belief that the book possesses the virtue of protecting from fire the house in which it, or a copy of it, is kept. He reedited the cabalistic treatises "Sefer ha-Malbush," "Sefer Noaḥ," "Sefer ha-Mazzalot," "Shi'ur Ḳomah," "Tefillot," and "Ma'asch Bereshit." In the same year he edited and published "Zohar he- Ḥadash," "Midrash ha-Ne'elam," "Sitre Torah," "Tiḳḳunim," "Liḳḳuṭim," and the Zohar on the Five Scrolls. His son Löb added to the "Zohar he- Ḥadash" a vocabulary to the two Zohars, extracted from the "Imre Binah" of Issachar Bär.
