Daniel 11:6 - Coke's Commentary on the Holy Bible

And in the end of years— After these wars had long lasted between Ptolemy and Antiochus Theus, they agreed to make peace; upon condition, that the latter should put away his former wife Laodice and her sons, and marry Berenice, Ptolemy's daughter; accordingly, he brought her to Antiochus, with an immense treasure, and thence received the appellation of dowry-giver. She did not, however, long retain her interest and power with Antiochus; for, after some time, in a fit of love he brought back his former wife with her children to court again. But neither did he stand, nor his arm, nor his seed; for Laodice, fearing the fickle temper of her husband, lest he should recal Berenice, caused him to be poisoned; and managed matters so as to fix her eldest son Callinicus on the throne: and, not content with this, she caused Berenice also to be murdered, and them that brought her; for her Egyptian women and attendants, endeavouring to defend her, were many of them slain with her: and he that begat her, or rather, he whom she brought forth; the son being murdered as well as the mother, by the order of Laodice: and he that strengthened her, &c. her husband Antiochus, or those who took her part, or rather her father, who died a little before, and who was excessively fond of her.
