1 Maccabees 10:51–58

⁵¹Then Alexander sent ambassadors to Ptolemy king of Egypt with the following message: ⁵²“Since I have returned to my kingdom and have taken my seat on the throne of my fathers, and established my rule—for I crushed Demetrius and gained control of our country; ⁵³I met him in battle, and he and his army were crushed by us, and we have taken our seat on the throne of his kingdom— ⁵⁴now therefore let us establish friendship with one another; give me now your daughter as my wife, and I will become your son-in-law, and will make gifts to you and to her in keeping with your position.”

⁵⁵Ptolemy the king replied and said, “Happy was the day on which you returned to the land of your fathers and took your seat on the throne of their kingdom. ⁵⁶And now I will do for you as you wrote, but meet me at Ptolemais, so that we may see one another, and I will become your father-in-law, as you have said.”

⁵⁷So Ptolemy set out from Egypt, he and Cleopatra his daughter, and came to Ptolemais in the one hundred and sixty-second year. ⁵⁸Alexander the king met him, and Ptolemy gave him Cleopatra his daughter in marriage, and celebrated her wedding at Ptolemais with great pomp, as kings do.
