Daniel 11:2, 10

“Now then, Daniel, I tell you the truth: Three more kings will rule in Persia, and then a fourth king will come. He will be much richer than all the kings of Persia before him and will use his riches to get power. He will stir up everyone against the kingdom of Greece.

“The sons of the king of the North will prepare for war. They will get a large army together that will move through the land very quickly, like a powerful flood. Later, that army will come back and fight all the way to the strong, walled city of the king of the South.
