This territory is called Samaria or more correctly 'Shomron' in Hebrew. We can see what the Jews are already doing there to hold on to it and make it fruitful. They are actually holding on to the land for Joseph's son Ephraim. There is a wonderful video of the towns of Judea and Samaria too.
There is actually a commandment in Jeremiah for Ephraim to turn to these cities and look to the highway. This is in Jeremiah 31. Then we can begin to think about a physical return to the land of the Shomron and greater Israel after World War 3, the war with Islam and the New World Order folks from Edom.
And the other reason that I have created this page is to support the Jews there. For more information visit הארץ.
