'Alliance' in the Bible

After some years they will form an alliance, and the daughter of the king of the South will go to the king of the North to seal the agreement. She will not retain power, and his strength will not endure. She will be given up, together with her entourage, her father, and the one who supported her during those times.

After an alliance is made with him, he will act deceitfully. He will rise to power with a small nation.
