Daniel 11:7, 13, 15

But when one of her relatives becomes king of the south, he will raise an army and enter the fortress of the king of the north and defeat him.

“A few years later the king of the north will return with a fully equipped army far greater than before.

Then the king of the north will come and lay siege to a fortified city and capture it. The best troops of the south will not be able to stand in the face of the onslaught.
