The Book of Mormon describes a journey by a group of people led by a prophet named Lehi from the Old World to the New World in approximately 600 B.C. The Book of Mormon also describes the journey of 2 other groups to America. One group was the people of Mulek (supposed by Bible authors to have died), who was the son of Zedekiah. The group left Jerusalem within a few years of Lehi's departure, but was not known to the people of Lehi until some time between 323 and 130 B.C. Another group described in great detail in the Book of Mormon, particularly in the constituent Book of Ether, is called the Jaredites. According to the Book of Mormon, the Jaredites came from the Tower of Babel in barges and inhabited the Western Hemisphere until their complete destruction through civil war, which occurred after the people of Mulek arrived in the New World. The only Jaredite to encounter the people of Mulek was named Coriantumr and he dwelt with them for "nine moons" before his death. The history of the Jaredites was reportedly recorded by a Jaredite prophet named Ether, whose record was abridged by the prophet Moroni (son of Mormon) many hundred years later and included in the Book of Mormon as the Book of Ether.
