Book of Mormon | Ether 8:18-22 (Bold emphasis added.)
The Book of Mormon is a sacred text of the Latter Day Saint movement, which, according to Latter Day Saint theology, contains writings of ancient prophets who lived on the American continent from approximately 2200 BC to AD 421.[1][2] It was first published in March 1830 by Joseph Smith as The Book of Mormon: An Account Written by the Hand of Mormon upon Plates Taken from the Plates of Nephi.[3] The Book of Mormon is one of the earliest of the unique writings of the Latter Day Saint movement, the denominations of which typically regard the text primarily as scripture, and secondarily as a historical record of God's dealings with the ancient inhabitants of the Americas.[4] https://en.wikipedia.org/wiki/Book_of_Mormon
