Prison of Middoni is a place of confinement in the land of Middoni where Aaron, Muloki, and Ammah were held. The Lord told Ammon that “thy brother Aaron, and also Muloki and Ammah are in prison,” and Ammon told Lamoni, “my brother and brethren are in prison at Middoni” (Alma 20:2-3). Lamoni traveled with Ammon toward Middoni, and the brethren were brought out of prison after Lamoni found favor with the king of the land (Alma 20:28).
Ammon’s brethren had been driven “from house to house, and from place to place” until they arrived in Middoni, where they were “bound with strong cords, and kept in prison for many days” (Alma 20:30). Aaron and certain brethren “suffered many things” in prison; after Lamoni and Ammon delivered them, they were fed and clothed (Alma 21:13-14).
