Judea

After the Captivity this name was applied to the whole of the
country west of the Jordan (Hag. 1:1, 14; 2:2). But under the
Romans, in the time of Christ, it denoted the southernmost of
the three divisions of Israel (Matt. 2:1, 5; 3:1; 4:25),
although it was also sometimes used for Israel generally
(Acts 28:21).

The province of Judea, as distinguished from Galilee and
Samaria, included the territories of the tribes of Judah,
Benjamin, Dan, Simeon, and part of Ephraim. Under the Romans it
was a part of the province of Syria, and was governed by a
procurator.
