This date derives from the Exodus story, specifically the day when Moses returned and found to Hebrews fighting. They knew he had killed an Egyptian and asked, "Who made you ruler over us?"
The prophetic significance of the date is the swearing in of the new United Nations General Secretary, Ban Ki-moon. He was now ruler over everyone.
Detailed timing and associated scripture follow below.
The swearing in ceremony took place on Thursday, December 14, 2006. This was 3 days ahead of the theoretical date suggested by the modern Exodus Plagues time line. The theoretical date is Sunday, and there is normally no UN session on Sunday.
13And when he went out the 2nd day, he looked, and saw 2 Hebrew men were quarreling together; and he said to him who did the wrong, Why do you beat your fellow?
14And he replied, Who made you a prince and a judge over us? Do you intend to kill me, as you killed the Egyptian yesterday? And Moses was afraid, and said, Surely this thing is known.
15Now when pharaoh heard this thing, he sought to slay Moses. But Moses fled from the presence of pharaoh, and went to the land of Midian; and he sat down by a well.
