The East was the South; Copper scroll study.
My theory is that the second copy of this scroll relates to the book of Isaiah, and a treasure room full of hidden scrolls. When the ark went missing, it's possible the original scrolls that were in it went missing as well. I am more inclined to believe the 'treasures' in the scroll had something to do with the price men had paid to obtain original scrolls or copies people said were from original scrolls.
My theory works off many different factors; To begin with the Essenes reigned within a time the Parthian reigned. The Parthian was also in the same territory of where originals journals from the ark may have gone in 586 BC. In my view the Essenes look like they might have actually been on the lookout to find the coming savior, Isaiah's Messiah. Taking the Liberty to try and bring a close to this story perhaps. So when somebody was chosen that might have potential, perhaps they were told of this treasure room of scrolls. If a man came forward and proclaimed to be the Messiah, perhaps these caves is where his spirit was tested. It is one thing to claim it, but another to come up empty with a key to understanding God and his word.
So one man while enduring this test of spirit wrote the copper scroll. As he looked out eastward he could easily imagine himself in this treasure room, even though he sat looking to the east of his cave at the Dead Sea. So if east is the south; then the mouth of the cave he sees himself in is to the north? What are the chances that the mouth of the cave he speaks of is in the south side of the hill/mountain?
Just a thought from the little book of Skeeter.
