The Lord reveals to Lehi that his sons should return to Jerusalem and enlist Ishmael's family in their journey so that those sons could marry Ishmael's daughters and have families. Ishmael's family consents to join them. Along the way, disagreements break out, and Laman and Lemuel lead a rebellion. They bind Nephi and leave him for wild animals to devour him, but Nephi is miraculously released. Laman and Lemuel repent, and the company completes their journey to join with Lehi and Sariah.
