A Dictionary of the Book of Mormon/Middoni
MIDDONI. A land of the Lamanites. Here Aaron, Muloki, and Ammah were imprisoned, and treated with great cruelty by its sin-hardened inhabitants. Directed by the revelations of God, Ammon, then in the land of Ishmael, determined to go and deliver his brethren. Lamoni, the converted king of that land, decided to accompany him, as he believed he had influence sufficient with Antiomno, king of Middoni, to obtain the release of the imprisoned missionaries. (B. C. 86.) On their way, Ammon and Lamoni met the latter's father, the supreme ruler of all the Lamanites, journeying from the land of Nephi (Lehi-Nephi) to the land of Ishmael. From the circumstance of this meeting it is presumable that Middoni lay somewhere between Ishmael and Nephi, and as it is spoken of as down, it was probably situated in some of the lower valleys, or north towards the wilderness that separated the lands of Nephi and Zarabemla. Arrived at the land of Middoni, Lamoni found favor with Antiomno and procured the release of Aaron and his associates. Though they had at first so cruelly treated the Nephite missionaries, the Lamanites of this land were among those who were converted to the Lord by their ministrations. (Alma, 23:10.)
