And in the end of years they shall join themselves together; for the king’s daughter of the south shall come to the king of the north to make an agreement: but she shall not retain the power of the arm; neither shall he stand, nor his arm: but she shall be given up, and they that brought her, and he that begat her, and he that strengthened her in these times.
In time, the south's king daughter will join the north's king for an agreement. However, she won't keep control of her army, nor will he or his army stand strong. They all will be handed over during this period.
