Do Biblical Prophecies Give West Bank to Jews?

Doesn't the biblical prophecy saying the Jews will return to the Holy Land include that they will return to the West Bank, the very land the the UN, by some measurements, gave to Israel's enemies a few days ago? 

Perhaps. After all, when the Tribes of Israel were allotted land back in Old Testament times, a fair share of the land given to the Tribe of Judah was in what today is the West Bank. The West Bank includes area that has been called the cradle of the Jewish people, the birthplace of Jewish history. If the prophecies are that the Jews will return to the land they were given, how do we suppose that does not include the area where their history began?

Another touch is that Bethlehem is in the West Bank, a touch that might be more significant to Christians than Jews, since Jews believe in Jesus only as a prophet, not as the Messiah. but, is Bethlehem, the birthplace of the Savior, not to even be included in the nation of Israel?

Perhaps the restoration of the Jews to their lands does, indeed, not include their having parts of the West Bank. But, to me, it does seem otherwise. It seems parts of the West Bank are part of the land promised them in the Bible.
