Samaria is one of the several standard statistical "areas" utilized by the Central Bureau of Statistics of the State of Israel. "The CBS also collects statistics on Judea-Samaria and the Gaza District. It has produced various basic statistical series on the territories, dealing with population, employment, wages, external trade, national accounts, and various other topics." Samaria is used by people who want to emphasize Israel's and the Jewish people's relationship with their land. For example, Samaria, along with Judea, is now more widely known, outside of Israel, by the neologism "West Bank."
According to Paul, the last words of Jesus before His ascension included Samaria:
6So when they met together, they asked him, "Lord, are you at this time going to restore the kingdom to Israel?" 7He said to them: "It is not for you to know the times or dates the Father has set by his own authority. 8But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth." 9After he said this, he was taken up before their very eyes, and a cloud hid him from their sight. -Acts 1:6-9
