In the Book of Mormon, Laman and Lemuel are the two eldest sons of Lehi and the older brothers of Sam, Nephi, Jacob, and Joseph. According to the text, they lived around 600 BC. They were notable for their rebellion against Lehi and Nephi, becoming the primary antagonists of the First and Second Books of Nephi. Their descendants became known as the Lamanites and Lemuelites, while the descendants of Nephi and their other brothers became the Nephites.
