Brothers claimed to hear the voice of an attending angel which proclaimed to him the fall of Babylon the Great, which was in fact London.
In similarity to modern British Israelists, Brothers asserted that the "hidden Israel" had no notion of its biological lineage and that part of his role would be to teach them of their true identity and lead them to the land of Canaan.
Brothers proclaimed himself to be Prince of the Hebrews, literal descendant of the Biblical House of David, and the Nephew of the Almighty, who would rule over Israel until the return of Jesus Christ.
London, Printed in the year of Christ 1794.Brothers began to attract quite a following, but due to his rejection of organisational work, and eccentric nature, he did not develop any sort of social movement.
But when Brothers predicted that, on 19 November 1795 he would be revealed as Prince of the Hebrews and Ruler of the world, and the date passed without any such manifestation, Sharp deserted him to become a religious follower of Joanna Southcott.
John Finlayson finally secured his release from the private asylum in 1806, and Brothers moved into his London home, where he died a lonely figure on 25 January 1824.
Finlayson then began a financial campaign against the Government, seeking payment of an enormous claim for his maintenance of Richard Brothers prior to his death.
