Yes I believe it is Bibical. When I play the song I sing "Manesseh" After a little Bible research and comparing it to the Sanctified Singers version, I thought it was the best candidate.

The song doesn't make sense in other ways like the line....Mary was a virgin she birthed the son of God, but that was not sufficient, she had to go with John. I don't think the bible talks about going with John. I love the song though. It's one of my favorite to play because it is so unusual.
