IV Maccabees 14:6-16

6 For just as hands and feet are moved sympathetically with the directions of the soul, so those holy youths agreed unto death for religion's sake, as through the immortal soul of religion.
7 O holy seven of harmonious brethren! for as the seven days of creation, about religion,
8 so the youths, circling around the number seven, annulled the fear of torments.
9 We now shudder at the recital of the affliction of those young men; but they not only beheld, and not only heard the immediate execution of the threat, but undergoing it, persevered; and that through the pains of fire.
10 And what could be more painful? for the power of fire, being sharp and quick, speedily dissolved their bodies.
11 And think it not wonderful that reasoning bore rule over those men in their torments, when even a woman's mind despised more manifold pains.
12 For the mother of those seven youths endured the rackings of each of her children.
13 And consider how comprehensive is the love of offspring, which draws every one to sympathy of affection,
14 where irrational animals possess a similar sympathy and love for their offspring with men.
15 The tame birds frequenting the roofs of our houses, defend their fledglings.
16 Others build their nests, and hatch their young, in the tops of mountains and in the precipices of valleys, and the holes and tops of trees, and keep off the intruder.
