Aram-Naharaim ( Aramaic: ארם נהריים) is a region that is mentioned five times in the Hebrew Bible or Old Testament. It is commonly identified with Nahrima mentioned in three tablets of the Amarna correspondence as a geographical description of the kingdom of Mitanni. In Genesis, it is used somewhat interchangeably with the names Paddan Aram and Haran to denote the place where Abraham stayed briefly with his father Terah's family after leaving Ur of the Chaldees, while en route to Canaan (Gen. 11:31), and the place to which later patriarchs obtained wives, rather than marry daughters of Canaan. Paddan Aram refers to the part of Aram-Naharaim along the upper Euphrates, while Haran is mainly identified with the ancient Assyrian city of Harran on the Balikh River. According to one rabbinical Jewish tradition, the birthplace of Abraham (Ur) was also situated in Aram-Naharaim.
