Laban (/ˈleɪ.bən/) was the name of a person in the first part of the Book of Mormon, a scripture of the Latter Day Saint movement. Although he only makes a brief appearance in the narrative, his brass plates would play an important role amongst the Nephites, who are the book's main protagonists.
In the book of First Nephi, chapters three and four, Laban is described as a notable citizen of Jerusalem who commanded great wealth and many servants. Among his possessions was a set of brass plates containing the genealogy of Lehi, a major character in the early portion of the Book of Mormon. Lehi, having left the city with his family in response to God's command, enjoined his four sons to return to Jerusalem and retrieve them: "For behold, Laban hath the record of the Jews and also a genealogy of my forefathers, and they are engraven upon plates of brass." Lehi furthermore stated that this injunction did not originate with himself, but with the Lord, who had spoken to him on this matter in a dream.
Lehi's two older sons, Laman and Lemuel, were reluctant to obey their father's order at first, fearful of Laban's power and ruthless reputation. However, Lehi's fourth son, Nephi, vowed that he would obey God's command: "For I know that the Lord giveth no commandments unto the children of men, save he shall prepare a way for them that they may accomplish the thing which he commandeth them." Accordingly, the four sons of Lehi set out for Jerusalem.
First, Laman went to Laban alone to request the records, but Laban cast Laman out of his house and threatened to kill him. Next, Nephi and his brothers offered all of their valuables to Laban in return for the brass plates. Laban took the family's goods but then refused to keep his end of the deal, ordering his men to slay Lehi's sons.
