The central idea of this booklet did not occur to Menasseh immediately on receiving John Dury’s letter. His first intention, as he explained in a letter dated November 25, 1649, was to write a treatise on the Dispersion of the Ten Tribes for the information of Dury and his friends. The volume, however, grew under his pen, and a week later he announced to Dury his larger plan. His letter gives a complete synopsis of the work, and he finishes up by informing Dury that “I prove at large that the day of the promised Messiah unto us doth draw near.”[38] Thus he had already made up his mind on a question which, only a few months before, he had assured Holmes was “uncertain,” and was intended to be uncertain. Holmes was at the time unaware of his conversion, for, on December 24, he wrote to him an expostulatory letter, in which, curiously enough, he advised him to study the Danielic Prophecies.[39] Still, Menasseh does not seem to have fully grasped the application of his treatise to the Resettlement question, for neither in the body of the work nor in the Spanish edition does he refer to it. It was only when he composed the Latin edition that his scheme reached maturity. To that edition he prefixed a dedication to the English Parliament, eulogising its stupendous achievements, and supplicating “your favour and good-will to our nation now scattered almost all over the earth.” The tract produced a profound impression throughout England. That an eminent Jewish Rabbi should bless the new Republican Government, and should bear testimony to its having “done great things valiantly,” was peculiarly gratifying to the whole body of Puritans. To the Millenarians and other sectaries it was a source of still deeper satisfaction, for their wild faith now received the sanction of one of the Chosen People, a sage of Israel, of the Seed of the Messiah. Besides the Latin edition which Dury distributed among all the leading Puritans, and which was probably read in Parliament, two English editions issued anonymously by Moses Wall were rapidly sold. Nevertheless, its effect proved transitory. Sober politicians, who still recognised that the new-fledged Republic had, as Fairfax said, “more public affairs” to despatch than the Jewish question, had begun to fear lest their hands might be forced by Menasseh’s _coup_. This feeling was strikingly reflected in a tract by Sir Edward Spencer, one of the members of Parliament for Middlesex. Addressing himself with feline affection “to my deare brother, Menasseh ben Israel, the Hebrewe Philosopher,” he expressed his readiness to agree to the admission of the Jews on twelve conditions artfully designed to strengthen the hands of the sectaries who believed that, besides the dispersion of the Jews, their conversion was also a necessary condition of the Millennium.[40] Spencer’s tract was the signal for a revulsion of feeling. Sadler, afterwards one of Menasseh’s firmest friends, threw doubts on the authenticity of Montezinos’s
