Mormon mentions that "holy prophets" helped King Benjamin establish peace in the land (Words of Mormon 1:16-18). Who were these prophets and when did they appear? It is hard to know specifically, but Amaleki seems to be one of them, either personally or by way of his turning the spiritual messages on the small plates over to King Benjamin (Omni 1:25-26).

[Words of Mormon 1:17]: Stiffneckedness:
According to Dr. Sami Hanna, an Egyptian who was especially schooled in the Arabic language, the word "stiffneckedness" is used many times throughout the Book of Mormon. If Joseph Smith had been writing his own book, he would likely have used "stubborn" or "inflexible." But in translating, he used the Semitic counterpart, the extremely awkward "stiffneckedness."
