Two Walls of the Exodus

1) The destruction of Sodom which is very likely Tall el-Hammam corresponding to Genesis 19 (see the essay at My Theological Essays);

2) The destruction of Jericho corresponding to Joshua 6.

The birth of Isaac in Genesis 21 cannot come before the meteoric airburst nuked Tall el-Hammam. The birth of Jacob, his twelve sons, the Sojourn, the Exodus and the Wandering follows that. And the Conquest kicks off with the walls of Jericho falling flat (as proven by excavations).

The Exodus must come between the total destruction of those two cities. If those events can be correctly dated, any Egyptian chronology or links to contemporary culture must be subservient to that date range.
