'Form' in the Bible

After some years have passed, they will form an alliance. Then the daughter of the king of the south will come to the king of the north to make an agreement, but she will not retain her power, nor will he continue in his strength. She, together with the one who brought her, her child, and her benefactor will all be delivered over at that time.

His intention will be to come with the strength of his entire kingdom, and he will form alliances. He will give the king of the south a daughter in marriage in order to destroy the kingdom, but it will not turn out to his advantage.
