There are no first-hand original texts of anything found in the Bible, therefore nothing is remotely reliable. However, we do have the original text for the Book of Mormon that Joseph Smith claimed God revealed to him, word by word, on a pebble in his hat. There have been thousands of subsequent alterations to God’s original words. Below is just one example of how Smith’s God spoke.
“And they were led by a man whose name was Coriantumr; and he was a descendant of Zarahemla; and he was a dissenter from among the Nephites; and he was a large and mighty man; therefore the king of the Lamanites, whose name was Tubaloth, who was the son of Ammoron. Now Tubaloth supposing that Coriantumr, he being a mighty man, could stand against the Nephites, insomuch with his strength, and also with his great wisdom, that by sending him forth, he should gain power over the Nephites; therefore he did stir them up to anger, and he did gather together his armies, and he did appoint Coriantumr to be their leader, and did cause that they should march down to the land of Zarahemla, to battle against the Nephites. And it came to pass that because of so much contention and so much difficulty in the government, that they had not kept sufficient guards in the land of Zarahemla; for they had supposed that the Lamanites durst not come into the heart of their lands to attack that great city Zarahemla.” (1830 Book of Mormon, pp.408-9 which now comprises Helaman 1:15-18).
I doubt any Mormon missionary ever recommended that in its original form as suitable reading for an investigator. It seems Smith’s God was as illiterate as the man himself.
