Redaction: Com repeats the basic storyline of Shule with regards to the people and prophets. The general makeup of the land is with the wicked, and so prophets are sent to convince the people to repent and return to God. The people not only do not repent, they turn on the prophets. Com, like Shule before him, succors the prophets, and his rule is blessed for his efforts. The parallelism between the two should not be seen as a poverty of imagination for Moroni, but rather as the result of his overriding purpose in telling this part of the story. The various dealings of the Jaredite kings have relevance to the spiritual mission of Moroni only if he can turn them into spiritual lessons. The repeating lesson highlights the importance of that meaning, and the importance Moroni gives to it.
Chronology: Com would be reigning from 440-410 B.C. according to the average reign chronology.
