Daniel 11:6

And in the end of years, that is, after several years have elapsed, they shall join themselves together, the king of the South and the king of the North forming a confederacy, when Antiochus II Theos, the second successor of Seleucus Nicator, married Berenice, the daughter of Ptolemeus Philadelphus; for the king's daughter of the South shall come to the king of the North to make an agreement, to establish just and peaceful relations by virtue of this marriage; but she shall not retain the power of the arm, neither shall he stand nor his arm, neither of them retaining the power acquired through their marriage and the joining of their forces; but she shall be given up, and they that brought her, and he that begat her, and he that strengthened her in these times, when the critical position in which he found himself suggested the marriage to him. Secular accounts set forth the situation as follows: "As soon as Ptolemy Philadelphus died in B. C. 247, Antiochus Theos expelled Berenice, and recalled the formerly rejected Laodice. The latter, however, aimed at further revenge, and to achieve it, she poisoned the king, had her son by him, Seleucus II Callinicus, declared his successor, and sent assassins against Berenice, who had fled to the sanctuary of Daphne. The latter queen was slain, together with her little son, and the hope of the Ptolemies to behold one of their lineage on the throne of the Seleucidae was thus wholly destroyed. "
