Manasseh continued to plead for the formal recognition of Jewish settlement in England, and he appeared before Oliver Cromwell in London in 1655 to argue his cause. While in England he wrote Vindiciae Judaeorum (1656; “Vindication of the Jews”) in answer to contemporary attacks on Jews, including William Prynne’s Short Demurrer. He returned to Holland in 1657, believing his mission to have been unsuccessful. His efforts, however, initiated the unofficial English acceptance of Jewish settlement and led to the granting of an official charter of protection to the Jews of England in 1664, after Manasseh’s death.
Sadler, a noted Hebraist, was associated with the phenomenon of ‘philosemitism’. This was also part of the Hartlib-Dury programme, described by Richard Popkin as aimed at making ‘Christians more aware of what Jews actually believed and practised. This, in turn, would make Christianity “less offensive” to the Jews.’
An Amsterdam rabbi, Menasseh ben Israel, was nominated for a chair at the proposed Jewish college in London (an unfulfilled design), part of a reformed university according to the Hartlib scheme. As Popkin remarks, it seems odd that the rabbi should haveconsidered joining a venture aimed at converting Jews, but he had difficulties with his own synagogue, partly because of his association with Christians. While in Holland in the 1640s Dury, who wished for the conversion of the Jews as well as the reconciliation of all Protestants, met Menasseh; he corresponded with him in 1649 on reports that the legendary ‘lost tribes’ of Israel had been identified in the Americas; this was important to the messianic dream of Menasseh and other Jews.
Another philo-semite, the English baptist divine Henry Jessey, addressed his book The Glory and Salvation of Jehuda and Israel to the ‘dear’ and ‘eminent’ nation of the Jews, in particular Menasseh. Jessey drew on rabbinic and kabbalistic prophecies to prove that these authorities supported Christian views about the Messiah; he believed that the Jews would be converted by 1658. He corresponded regularly with Menasseh who sent him a copy of his book Esperanca de Israel – The Hope of Israel; this work, also drawing on prophecy, aimed to show ‘that the day of the promised [Jewish] Messiah unto us doth draw near.’ Both books were published in 1650.6

Henry Jessey or Jacie (1603 in West Rowton, Yorkshire – 1663) was one of many English Dissenters. He was a founding member of the Puritan religious sect, the Jacobites. Jessey was considered a Hebrew and a rabbinical scholar. His active philosemitism has led him to be described as \"among Israel's greatest seventeenth-century benefactors.\"[1]
