In the third year of King Cyrus of Persia a message was revealed to Daniel (who was also called Belteshazzar). This message was true and concerned a great war. He understood the message and gained insight by the vision.

"Then he said, "Do you understand why I came to you? Soon I'll return to fight the prince of Persia. I'm going forth to war and take note the prince of Greece is coming!

And the king of the south will be moved with wrath, and will come out and make war on him, on this same king of the north: and he will get together a great army, but the army will be given into his hand.

He'll invade the most prosperous areas of the province during a time of tranquility, accomplishing what neither his predecessors nor his ancestors ever could. He'll distribute war spoils, booty, and wealth to them, and he'll plot the overthrow of fortresses, though only for a time.

He'll encourage himself against the southern king by raising a large army. As a result, the southern king will mobilize for war with a large and powerful army, but he won't succeed because they will devise elaborate schemes against him.

Insightful people will impart understanding to many, though they'll fall by sword, by fire, by captivity, and as war booty for a while.

And at the time of the end, the king of the south will make an attack on him: and the king of the north will come against him like a storm-wind, with war-carriages and horsemen and numbers of ships; and he will go through many lands like overflowing waters.
