Judaea or Judea
(from Judah), a territorial division which succeeded to the overthrow of the ancient landmarks of the tribes of Israel and Judah in their respective captivities. The word first occurs in Daniel 5:13 (Authorized Version “Jewry”) and the first mention of the “province of Judea” is in the book of Ezra (Ezra 5:8). It is alluded to in Nehemiah 11:3 (Authorized Version “Judah”). In the apocryphal books the word “province” is dropped, and throughout them and the New Testament the expressions are “the land of Judea” and “Judea.” In a wide and more improper sense, the term Judea was sometimes extended to the whole country of the Canaanites, its ancient inhabitants, and even in the Gospels we read of the coasts of Judea “beyond Jordan” (Matthew 19:1; Mark 10:1). Judea was, in strict language, the name of the third district, west of the Jordan and south of Samaria. It was made a portion of the Roman province of Syria upon the deposition of Archelaus, the ethnarch of Judea, in A.D. 6, and was governed by a procurator, who was subject to the governor of Syria.
