Laman, the oldest son of Lehi and Sariah, was stubborn, hard-hearted, and did not believe in the righteous teachings of his father, Lehi. The Book of Mormon records that Laman was so rebellious that he refused to listen when an angel from the Lord told him to change his behavior. Laman was a troublemaker and seldom helped his family. His wickedness caused his parents a great deal of pain and sorrow.
