Tower of Bable was in Land of Shinar (Babylonia) noted in Genesis 11: 1-10. Noah’s descendants established cities here after the flood (Genesis 10: 10).
After the death of Yahshua and the resurrection of YahwehShua Messiah Jude traveled Mesopotamia 10 years preaching and converting many to the resurrected YahwehShua Messiah!
