According to the Book of Mormon, Lehi was a prophet who lived in Jerusalem during the reign of King Zedekiah. In First Nephi, Lehi is rejected for preaching repentance and he leads his family, including Sariah, Laman, Lemuel, Sam, and Nephi, into the wilderness. He sends his sons back to recover the plates of brass and once more for the family of Ishmael. As they travel, Lehi has a vision of the tree of life in which most of his family, excepting Laman and Lemuel, accepts God. He also prophesies Christ's coming 600 years in the future.

The Book of Mormon is a religious text of the Latter Day Saint movement, first published in 1830 by Joseph Smith as The Book of Mormon: An Account Written by the Hand of Mormon upon Plates Taken from the Plates of Nephi.
