Also remember that today's Bible was retold by a game of telephone before being written down. It was then written in a tongue the average person on the street could not read, this was so that they could not translate it themselves and were at the mercy of a preacher to tell them what it said. It was illegal to translate and/or distribute a copy of the texts.
This is all to say that had any of it been real, it is more than likely to have been reshaped over the years, before white nationalists have now added their own spin.
