Aminadi interpreted “the writing which was upon the wall of the temple, which was written by the finger of God” (Alma 10:2). He was a descendant of Nephi, the son of Lehi who came out of the land of Jerusalem (Alma 10:3).
Aminadi is named only as an ancestor of Amulek, the missionary companion of Alma the Younger, who traced his line to Aminadi through his father Giddonah and grandfather Ishmael (Alma 10:2). The record gives no further detail about Aminadi or the writing he interpreted.
