I Maccabees 10:49-59

49 And after the two kings had joined battle, Demetrius' host fled: but Alexander followed after him, and prevailed against them.
50 And he continued the battle very sore until the sun went down: and that day was Demetrius slain.
51 Afterward Alexander sent ambassadors to Ptolemee king of Egypt with a message to this effect:
52 Forasmuch 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;
53 For 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:
54 Now 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.
55 Then 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.
56 And 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.
57 So Ptolemee went out of Egypt with his daughter Cleopatra, and they came unto Ptolemais in the hundred threescore and second year:
58 Where 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.
59 Now king Alexander had written unto Jonathan, that he should come and meet him.
