Thou wast born of woman
But swords I smile at, weapons laugh to scorn,
Brandish’d by man that’s of a woman born.

– William Shakespeare

Macbeth, Act 5, Scene 7. Having slain Young Siward, Macbeth rejoices in his own invulnerability. An arrogant Macbeth gloats over the boy’s body and continues to delude himself that he cannot be harmed by anyone born of woman – as told in the Witches’ prophecy.
