II Samuel 18:33

33 The king was shaken. He went up to the room over the gateway and wept. As he went, he said: "O my son Absalom! My son, my son Absalom! If only I had died instead of you - O Absalom, my son, my son!"

33 Then the king was much moved, and went up into the room over the door, weeping, and saying, O my son Absalom, my son, my son Absalom! if only my life might have been given for yours, O Absalom, my son, my son!
