Originally the name ‘Mesopotamia’ was given to the fertile land around the upper reaches of the Euphrates and Tigris Rivers (Gen 24:10; Deut 23:4; Judg 3:8-10; 1 Chron 19:6). By New Testament times it applied to the whole of the Euphrates-Tigris valley, so that even the city of Ur, which was near the mouth of the Euphrates, was considered to be in Mesopotamia (Acts 2:9; 7:2). (For details see ARAM; ASSYRIA; BABYLON; EUPHRATES; SYRIA; TIGRIS.)
