IV Maccabees 15:10

10 For they were both just and temperate, and manly, and high-minded, and fond of their brethren, and so fond of their mother that even unto death they obeyed her by observing the law.

IV Maccabees 15:10 In-Context

9 Not but that, on account of the excellent disposition to the law, her maternal affection toward them was increased.
10 For they were both just and temperate, and manly, and high-minded, and fond of their brethren, and so fond of their mother that even unto death they obeyed her by observing the law.
11 And yet, though there were so many circumstances connected with love of children to draw on a mother to sympathy, in the case of none of them were the various tortures able to pervert her principle.
12 But she inclined each one separately and all together to death for religion.
