Eber-Nari

Eber-Nari (Akkadian), also called Abar-Nahara (Aramaic) or Aber Nahra (Syriac), was a region of the ancient Near East. Translated as "Beyond the River" or "Across the River" in both the Akkadian and Aramaic languages, it referred to the land on the opposite side of the Euphrates from the perspective of Mesopotamia and Persia. In this context, the region is further known to modern scholars as Transeuphratea (New Latin: ; or more rarely ; ). Functioning as a satrapy, it was originally administered by the Neo-Assyrian Empire before being absorbed by the Neo-Babylonian Empire and then by the Achaemenid Empire. During the Greek conquest of Persia, Eber-Nari was, like the rest of the Achaemenid Empire, annexed by the Macedonian Empire of Alexander the Great. It was later dissolved by the Seleucid Empire, which incorporated it into Syria, along with Assyria.

In the "DSf" Achaemenid royal inscription, the Akkadian Eber-Nari is referred to as Athura or Athuriya in Old Persian and as Aššur in Elamite. The Targum Onkelos, an Aramaic translation of the Torah, lists Nineveh, Calah, Reheboth, and Resen as being in the Athura jurisdiction.
