My bank is still Bank Leumi.
Banks are for financial transactions, loans, savings and investments.
A river has a "bank" but that surelyy does not extend for dozens of miles, up and down hills.
Judea and Samaria are the historical and geographical names of the area I live in, posrtions of the Land of Israel not yet under full Israel sovereignty. They are where Jews have lived for over 3000 years, very rarely not residing there and most recently, banned from living there due to a Jordanian occupation - illegal, I might add, between 1948-1967.
Jews lived in Gaza, in Hebron in Judea and Shchem of Samaria up until 1929 for many centuries.
They are not the "West Bank", a foreign term, one applied in April 1950 by a former Saudi Arabian who invaded Transjordan in November 1920 and,, incidentally, stymied the political aspirations of the Arabs of the Mandate of Palestine.
If you want to use the term "west" in describing the territory of the Land of Israel west of the Jordan River, it is not the "West Bank" but:
20 And the west side shall be the Great Sea, from the border as far as over against the entrance of Hamath. This is the west side.
That's from Ezekiel/Yechizkel 47:20.
