Letter from John Samuel to Isaac Leeser This eleven-page letter, written in English and Hebrew, discusses the principles of prayer and the structure of the liturgy. The writer, Isaac Mayer Wise, lays out his ideas for a new liturgy, emphasizing the importance of hymns and praises to God, and rejecting the inclusion of curses or supplications. He also advocates for the use of Hebrew in prayer, believing that the language itself elevates the experience. The letter is addressed to Isaac Leeser and John Samuel and includes additional correspondence from Joseph and LJ. There are also sections discussing the school of Padua and Wise's own writings, including his history of the Israelites and his views on Jewish jurisprudence.
