Daniel 11:5-6

5Then the king who rules in the south will become strong. But one of his own army officers will become even stronger. That officer will rule a greater kingdom than the king of the south.

6After some years, the king of the south and the king of the north will agree to be friends. The king of the south's daughter will go to marry the king of the north. That would make their agreement strong. But the plan will fail. She will lose her authority. Her husband will no longer rule as king. Someone will kill her, her husband, her child and the servants who helped her.
