IV Maccabees 15:13-23

13 O holy nature and parental feeling, and reward of bringing up children, and unconquerable maternal affection!
14 At the racking and roasting of each one of them, the observant mother was prevented by religion from changing.
15 She beheld her children's flesh dissolving around the fire; and their extremities quivering on the ground, and the flesh of their heads dropped forwards down to their beards, like masks.
16 O thou mother, who wast tried at this time with bitterer pangs than those of parturition!
17 O thou only woman who hast brought forth perfect holiness!
18 Thy first-born, expiring, turned thee not; nor the second, looking miserable in his torments; nor the third, breathing out his soul.
19 Nor when thou didst behold the eyes of each of them looking sternly upon their tortures, and their nostrils foreboding death, didst thou weep!
20 When thou didst see children's flesh heaped upon children's flesh that had been torn off, heads decapitated upon heads, dead falling upon the dead, and a choir of children turned through torture into a burying ground, thou lamentedst not.
21 Not so do siren melodies, or songs of swans, attract the hearers to listening, O voices of children calling upon your mother in the midst of torments!
22 With what and what manner of torments was the mother herself tortured, as her sons were undergoing the wheel and the fires!
23 But religious reasoning, having strengthened her courage in the midst of sufferings, enabled her to forego, for the time, parental love.
