1 Maccabees 10:51–58

⁵¹Afterward Alexander sent ambassadors to Ptolemee king of Egypt with a message to this effect: ⁵²Forasmuch as I am come again to my realm, and am set in the throne of my progenitors, and have gotten the dominion, and overthrown Demetrius, and recovered our country; ⁵³For after I had joined battle with him, both he and his host was discomfited by us, so that we sit in the throne of his kingdom: ⁵⁴Now therefore let us make a league of amity together, and give me now thy daughter to wife: and I will be thy son in law, and will give both thee and her as according to thy dignity.

⁵⁵Then Ptolemee the king gave answer, saying, Happy be the day wherein thou didst return into the land of thy fathers, and satest in the throne of their kingdom. ⁵⁶And now will I do to thee, as thou hast written: meet me therefore at Ptolemais, that we may see one another; for I will marry my daughter to thee according to thy desire.

⁵⁷So Ptolemee went out of Egypt with his daughter Cleopatra, and they came unto Ptolemais in the hundred threescore and second year: ⁵⁸Where king Alexander meeting him, he gave unto him his daughter Cleopatra, and celebrated her marriage at Ptolemais with great glory, as the manner of kings is.
