A Holy Temple on Mount Moriah has been discovered. The stone Temple is dated to the time of Shem-MalchiTzedek and went out of service after Jacob was exiled to Egypt.
The city of Ai is crucial to Biblical geography, but has never been discovered. New evidence changes much of what we understand about the location of Ai and Beit El.
These are the various sources that support the recent archaeological discovery of the matzevah located in the City of David, Jerusalem, most likely the one erected by Jacob.
Beit El is important to Jacob. In his encounter with it, the name appears in 8 different verses among which he names it on three different occasions. But it's location remains confused and sometime controversial.
