Nimrod (Hebrew: נמרוד, Nimrōḏ; Greek: Νεβρωδ, Nebrōḏ; Arabic: نمرود, Nimrūḏ; "Name means::rebellion") is described in Genesis 10:8-12 as a great hunter, warrior, and leader, who founded several cities in Mesopotamia, including Founder of::Babylon and Founder of::Nineveh.
Nimrod is also described in verse 8 as being the son of Cush, but he is not listed in Cush's genealogy in Genesis 10:6 . This may indicate that another Cush is referred to in verse 8, or that Nimrod was descended from Cush via some generations that aren't listed (as was sometimes done in Biblical genealogies). All of the sons listed in verse 6 settled in Africa, while Nimrod's kingdom is clearly in Mesopotamia. The most likely explanation is that Nimrod was indeed a son of Cush, but because of some quarrel he became estranged, and so settled elsewhere; this estrangement also could explain Nimrod's exclusion from verse 6.
Some scholars have speculated that Nimrod was the Hebrew name for Sargon I of Akkad, a leader who came from western lands to establish a kingdom in Mesopotamia. However, Sargon is generally considered to be a Semite (a descendant of Shem), not a descendant of Ham via Cush, as Nimrod seems to be.
