'Alliance' in the Bible

After some years the Syrian king of the North and the Egyptian king of the South will make an alliance; the daughter (Berenice) of the king of the South will come to the king of the North to make an equitable and peaceful agreement (marriage); but she will not retain the power of her position, nor will he retain his power. She will be handed over with her attendants and her father as well as he who supported her in those times.

After an alliance is made with him he will work deceitfully, and he will go up and gain power with a small force of people.
