And the king was much moved, and went up to the chamber over the gate, and wept: and as he went, thus he said, O my son Absalom, my son, my son Absalom! would God I had died for you, O Absalom, my son, my son!

Augustine of Hippo
AD 430
When King David had endured this affliction from his wicked and treacherous son, he had not only tolerated his uncontrolled passion but even lamented his death. He was not held ensnared by a carnal jealousy, since it was not the outrages inflicted on him, but rather the sins of his son that troubled him. For he had forbidden that his son be killed if he were conquered in order that opportunity for repentance might be reserved for him after he was vanquished. Since this was impossible, he did not grieve because of his bereavement in the death of his son but because he realized into what punishments such a wickedly adulterous and murderous soul was precipitated.
