This prayer by Rabbi Sabato Morais (1828-1897), of Congregation Mikveh Israel in Philadelphia, was initially delivered on 15 April 1862 (the first day of Passover) at the conclusion of a sermon later printed in The Philadelphia Inquirer on 23 April 1862. A copy of that sermon was preserved in the Sabato Morais Ledger (p. 22, clip no. 23). (The prayer was also read by President Abraham Lincoln, who sent Rabbi Morais an acknowledgment). The letter was read into the congressional record on 29 February 1944 by Arthur G. Klein (1904-1968, D-NY) after it was brought to light by Moshe Davis at the 44th annual meeting of the American Jewish Historical Society on 12-13 February 1944 (Lincoln’s Birthday). . . .
