He shall also set his face to enter with the strength of his whole kingdom, and upright ones with him; thus shall he do: and he shall give him the daughter of women, corrupting her: but she shall not stand on his side, neither be for him. He shall also set his face to enter - Antiochus purposed to have marched his army into Egypt; but he thought it best to proceed by fraudulence, and therefore proposed a treaty of marriage between him and his daughter Cleopatra, called here the daughter of women, because of her great beauty and accomplishments. And this he appeared to do, having "upright ones with him." Or, as the Septuagint have it και ευθεια παντα μετ' αυτου ποιησει, "and he will make all things straight with him;" that is, he acted as if he were influenced by nothing but the most upright views. But he intended his daughter to be a snare to Ptolemy, and therefore purposed to corrupt her that she might betray her husband.
But she shall not stand on his side - On the contrary, her husband's interests became more dear to her than her father's; and by her means Ptolemy was put upon his guard against the intentions of Antiochus.
