Nimrod (ˈnɪmrɒd; ; ܢܡܪܘܕ; Numrūd) is a biblical figure mentioned in the Book of Genesis and Books of Chronicles. The son of Cush and therefore a great-grandson of Noah, Nimrod was described as a king in the land of Shinar (Mesopotamia). The Bible states that he was "a mighty hunter before the Lord [and] ... began to be mighty in the earth". Later extra-biblical traditions identified Nimrod as the ruler who commissioned the construction of the Tower of Babel, which led to his reputation as a king who was rebellious against God.
Nimrod has not been attested in any historic, non-biblical registers, records or king lists, including those of Mesopotamia itself which are both considerably older and more diverse than the later biblical texts. Historians have failed to match Nimrod with any historically attested figure, although one recent suggestion among the exclusively Mesopotamian figures is Naram-Sin, grandson of Sargon.
Several ruins of the Middle East have been named after him during the Islamic Era.
The first biblical mention of Nimrod is in the Table of Nations. He is described as the son of Cush, grandson of Ham, and great-grandson of Noah; and as "a mighty one in the earth" and "a mighty hunter before the Lord". This is repeated in the First Book of Chronicles 1:10, and the "Land of Nimrod" used as a synonym for Assyria or Mesopotamia, is mentioned in the Book of Micah 5:6:
And they shall waste the land of Assyria with the sword, and the land of Nimrod in the entrances thereof: thus shall he deliver us from the Assyrian, when he cometh into our land, and when he treadeth within our borders.
Genesis says that the "beginning of his kingdom" (reshit mamlakhto) were the towns of "Babel, Erech, Akkad and Calneh in the land of Shinar" (Mesopotamia) (Gen 10:10)—understood variously to imply that he either founded these cities, ruled over them, or both. Owing to an ambiguity in the original Hebrew text, it is unclear whether it is he or Ashur who additionally built Nineveh, Resen, Rehoboth-Ir and Calah (both interpretations are reflected in various English versions).
