1 Nephi 1:13; “And he read, saying: Wo, wo, unto Jerusalem, for I have seen thine abominations! Yea, and many things did my father read concerning Jerusalem—that it should be destroyed, and the inhabitants thereof; many should perish by the sword, and many should be carried away captive into Babylon.”
Jeremiah 13:27; “I have seen thine adulteries, and thy neighings, the lewdness of thy whoredom, and thine abominations on the hills in the fields. Woe unto thee, O Jerusalem! wilt thou not be made clean? when shall it once be?”
Jeremiah 27:8; “And it shall come to pass, that the nation and kingdom which will not serve the same Nebuchadnezzar the king of Babylon, and that will not put their neck under the yoke of the king of Babylon, that nation will I punish, saith the LORD, with the sword, and with the famine, and with the pestilence, until I have consumed them by his hand.”
How did Lehi read the writings of Jeremiah in the supposed brass plates when they left in 600 BC? Jeremiah was written anywhere from BC 630 to BC 580 leaving a lot of room for speculation. Furthermore the writings of Nephi are far too similar to believe God would use the same phrases in sentence structure while contradicting Himself at the same time.
The other problem is found in the total disregard and disobedience to what the prophet Jeremiah said! Why did Lehi leave when Jeremiah was warning everyone to stay? Those who left Jerusalem on their own met death while those who heeded his warning were taken into captivity for 70 years and then returned to Jerusalem just as God promised – Jeremiah 29:10-11.
This is the only group of Israelites who disobeyed God and lived. There’s no other historical evidence of anyone living through the siege except for the claims of Joseph Smith in the Book of Mormon.
Jeremiah was writing as early as 627 BC so it is possible in the 27 years that his record could be spread just about anywhere making the claim in the Book of Mormon true. Also the Book of Mormon said around 600 BC. If words matter I would suggest that 575 ore even 550 BC could be still an accurate time frame when they left. I’m fact every date in the Book of Mormon used says it’s about this time. There is no definite date mentioned in the book so you can only speculate. And speculation doesn’t make the Book of Mormon wrong. It actually makes it more correct considering the word “about” is a vague term. At least the Book of Mormon was translated by the gift of translation and the power of God. The Bible can’t claim that. It was written by men who shared what they thought was the only stuff we need to know when in fact there is an abundance of text that most have never read because let’s be real most haven’t even read the Bible let alone the Book of Mormon and further to mention other text left out of the Bible. Some of that is possibly plane and precious but perhaps long lost.
