According to the Book of Mormon, Chemish was a Nephite record keeper. He received the Book of Mormon record from his brother Amaron, and penned a single verse in the Book of Omni (Omni 1:9) before passing the record to his son Abinadom:
<blockquote>9 Now I, Chemish, write what few things I write, in the same book with my brother; for behold, I saw the last which he wrote, that he wrote it with his own hand; and he wrote it in the day that he delivered them unto me. And after this manner we keep the records, for it is according to the commandments of our fathers. And I make an end.
