I found this site while surfing the Internet tonight. The owner has been translating the Book of Mormon into Hebrew. I cannot guarantee its accuracy and his site says he needs help proofreading the translation. His site contains many resources on Judaism and Mormonism.
Update: This is Tom Irvine’s ongoing effort to translate the Book of Mormon into Hebrew. This is only a partial translation of the Book of Mormon into Hebrew. This is NOT endorsed by the Church of Jesus Christ of Latter-day Saints nor is it the official translation of the Church. If you would like to proofread or help in the translation please contact him. For more information please visit his site.
