'Alliance' 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.

After entering into an alliance with him, he will behave treacherously; he will ascend to power with only a small force.
