Catena Aurea on Luke 11:45–54: Athanasius of Alexandria

Now if they kill, the death of the slain will cry out the louder against them; if they pursue, they send forth memorials of their iniquity, for flight makes the pursuit of the sufferers to redound to the great disgrace of the pursuers. For no one flees from the merciful and gentle, but rather from the cruel and evil-minded man. And therefore it follows, That the blood of all the prophets who have been slain from the foundation of the world may be required of this generation.
