According to some Book of Mormon scholars, “Paanchi” in the Book of Mormon may derive from the Egyptian name p3-‘nh. Which became a popular name “from the Twenty-First through Twenty-Seventh Dynasties.”
Here is the entry for p3-‘nh in Hermann Ranke, Die
Ägyptischen Personennamen, 3 vols. (Glückstadt: J. J. Augustin Verlag,
1935), 1:103
