IV Maccabees 4:25

25 for even women, because they continued to circumcise their children, were flung down a precipice along with them, knowing beforehand of the punishment.

IV Maccabees 4:25 In-Context

23 And having subdued them, he established a decree that if any of them lived according to the laws of his country he should die.
24 And when he could by no means destroy by his decrees the obedience to the law of the nation, but saw all his threats and punishments without effect,
25 for even women, because they continued to circumcise their children, were flung down a precipice along with them, knowing beforehand of the punishment.
26 When, therefore, his decrees were disregarded by the people, he himself compelled by means of tortures every one of this race, by tasting forbidden meats, to abjure the Jewish religion.
