The deaths of Nadab and Abihu also land prophetically at September 11, 2001. Unauthorized fire? Perhaps America's marines recently stationed in Jerusalem. Like the other sins, holding to a form of godliness, but denying its power.
There are several other side time lines operating through this period. One of these time lines provides an additional story. Between the time the Tabernacle was set up and the time of the first departure we expect to see the replay of the consuming of Nadab and Abihu by fire from the Lord.
This is not clearly dated in the the Bible story, the earliest prophetic date it could replay was August 23, 2001. The latest hits prophetically at October 4, 2001, with the prophetic replay of the first departure.
The "two" columns being brought down, the "two" cities being burned suggest the parallel stories to the burning of the two sons of Aaron, Nadab and Abihu. So we can assign the Nadab and Abihu story at September 11, 2001.
