Isaiah 19:2

And I will set the Egyptians against the Egyptians, inciting them to civil war and anarchy such as we are told of by secular historians; and they shall fight every one against his brother and every one against his neighbor; city against city and kingdom against kingdom. All this was fulfilled at the beginning of the seventh century before Christ, about the time before Nebuchadnezzar's invasion, when Egypt was divided into twelve kingdoms and into forty-two nomes, or districts, between some of whom there was always dissension, and real peace was not established even after Psammetichus had become sole ruler of the country.
