This prayer by Rabbi Sabato Morais was offered on US Independence Day (4 July 1863) at the conclusion of a sermon reguested by the “Philadelphia Union League” and delivered before Congregation Mikveh Israel, that was published in The Jewish Messenger on 10 July 1863. July 4th, 1863, was the day following the Battle of Gettysburg, and hand’t yet been recognized as the crucial turning point in the defeat of the Confederacy during the Slaveholder’s Revolt. It was preserved by Rabbi Morais in his ledger (page 22, clipping 023), an archive of newsclippings recording material he contributed to the press, among other announcements.
