Why God Sent for Them The reason Ishmael's family was brought into the wilderness
After Lehi's sons had successfully retrieved the brass plates, God told Lehi to send his sons back to Jerusalem again — this time for Ishmael and his household. The stated reason is direct: "that he might take one of the daughters of Ishmael to wife; that they might raise up seed unto the Lord in the land of promise" (1 Nephi 7:1). God was thinking about the next generation before the current generation had even survived the wilderness. The daughters of Ishmael were not an afterthought. They were the necessary element for the plan to have a future.
Ishmael agreed to come. His family came — his wife, his daughters, his sons and their families. They joined Lehi's camp in the wilderness. The marriages happened: Nephi married one of the daughters, his brothers married others. From that point forward, the two families traveled, argued, prayed, mourned, converted, and eventually divided together. The daughters of Ishmael are woven into every chapter of that story, though the narrative names them rarely and describes them individually almost never.
The civilization that the Book of Mormon documents — Nephites, Lamanites, a thousand years of history — traces back to these women's bodies and these women's choices to keep moving. Without them, the Lehite people are four men and an aging couple, who die in the wilderness and are forgotten. The daughters of Ishmael are the reason that does not happen.
