Jacob Emden Ashkenazi (abbreviated to Jabez; born 1698, died 1776) resembled his father Chacham Zevi, as a branch its parent stem; or rather he made the father whom he admired extravagantly his model in everything. The perverted spirit of the age prevented his following his natural bent and inspirations. A true son of the Talmud, he seriously believed that a Jew ought to occupy himself with other branches of knowledge only during "the hour of twilight," and considered it unlawful to read newspapers on the Sabbath. He, too, was well versed in the Talmud, and set a high value on the Kabbala and the Zohar, of the dangerous extravagances of which he at first knew nothing. Philosophy, although he possessed no knowledge of it, was an abomination to him. In his perverseness he maintained it to be impossible that the philosophical work, "The Guide," could have been composed by the orthodox rabbi, Maimuni. In character he was just, truth-loving, and staunch, herein forming a sharp contrast to Jonathan Eibeschütz. Whatever he considered as truth or false, he did not hesitate forthwith to defend or condemn with incisive acuteness; it was contrary to his nature to conceal, dissimulate, hide his opinions, or play the hypocrite. He differed from Eibeschütz in another respect. The latter was agreeable, pliant, careless, cheerful, and sociable; Emden, on the contrary, was unsociable, unbending, earnest, melancholy, and a lover of solitude. Well-to-do, and maintaining himself by his business, Emden was always disinclined to undertake the office of a rabbi. He was too well aware of his own craving for independence, his awkwardness, and impetuosity. Only once was he induced to accept the office of rabbi, in Emden (from which he derived his surname); but he relinquished it after a few years on account of his dislike to the work and from ill-health, and settled in Altona. He obtained from the king of Denmark the privilege of establishing a printing-press; built a house with a private synagogue, and, with his family and a few friends, formed a community within the community. He indeed visited the exchange, but he lived enwrapped in a dreamworld of his own.
