The Book of Mormon starts in Jerusalem at around 600 B.C. before it was destroyed and the people taken captive or killed.  Lehi a prophet of God was warned to take his family into the wilderness.

He shortly was commanded to return and convince or invite Ishmael and his family to join them in the wilderness.  They traveled near the Red Sea at times.  After a period of time Ishmael died.

The Book of Mormon records in First Nephi 16:34  “And it came to pass that Ishmael died, and was buried in the place which was called Nahom.”

Early critics of the Book of Mormon scoffed and claimed that Joseph Smith was a fraud and a liar.  Now we can clearly see that this evidence indicates that he was not.

Please rely on God for all truth.
