A Dictionary of the Book of Mormon/Laman, River
LAMAN, RIVER. A small Arabian river which emptied into the upper waters of the Red Sea. When Lehi and his little colony had traveled for three days in the wilderness which bordered on the Red Sea, they reached a pleasant valley through which this stream flowed, and Lehi gave to it the name of Laman, in honor of his eldest son. In the valley the company rested for some time; and it was during their sojourn here that Nephi and his brothers twice returned to Jerusalem — once for the plates of brass, and once for Ishmael and his family. When, by the Lord's command, Lehi's party continued their journey, they crossed the river Laman and proceeded southward.
