Several decapitations and dismemberments are also described in the Book of Mormon. In chapter 4 of the First Book of Nephi, the prophet Nephi is commanded by the Spirit to kill a man named Laban, whom he decapitates. In Ether chapter 15, the warrior Coriantumr, who is the last survivor of the Jaredites, decapitates Shiz. In Alma chapter 17, Ammon (a Nephite missionary) defends a Lamanite king's livestock by cutting off the arms of several thieves and killing several others with a sling.
