No. I think what Moses wrote is all 100% what he wrote.
Did he write Genesis? Did he put together the oral stories that were told?
BTW, I often thought that God picked the Hebrews specifically because they were so good at memorizing stories and history. There was no written history back then.
Did you know about Mathew's geneology?
Find out about it....it's not inerrant...it's just not complete.
This could be true for other "stories" as well.
Did you know that Matthew is written with the Jews in mind and only includes their history which starts with Abraham? It records the Lord’s royal lineage of King David through Abraham.
