According to the Book of Mormon, Shiblon was a Nephite missionary and record-keeper. He was the second son of Alma the Younger, who was the first chief judge. In the 17th year of the reign of the judges, or 74 BC, Shiblon went with his younger brother Corianton and his father Alma, along with 5 others, on a mission to teach the word of God to the apostate Zoramites in the land of Antionum, while his older brother Helaman stayed behind. The other members of the group consisted of Amulek, Zeezrom, Ammon, Aaron, Omner, and Himni. The group witnessed the peculiar way that the Zoramites worshiped in their synagogues, including the prayers offered on the Rameumptom.
In a BYU speech entitled No Less Serviceable, Howard W. Hunter gave the following recognition to Shiblon: "Many make their contributions in unsung ways... We don't know much about Shiblon, the faithful son of Alma who is sandwiched between Helaman, the future leader, and Corianton, the transgressor; but it is significant that he is described as a 'just man, and he did walk uprightly before God'" (Alma 63:2).
