And David went up by the ascent of mount Olivet, and wept as he went up, and had his head covered, and he went barefoot: and all the people that were with him covered every man his head, and they went up, weeping as they went up.
All Commentaries on 2 Samuel 15:30 Go To 2 Samuel 15
Cyril of Jerusalem
AD 386
Again, after Absalom’s rebellion, when David was in flight, with many possible routes before him, he chose to make his escape by the Mount of Olives, as good as invoking in his own mind the Deliverer who should from there ascend into the heavens. And when Shimei cursed him bitterly he said, “Let him be.” For he knew that forgiveness is for those who forgive.… As, then, brothers, you have many examples of people who have sinned and then repented and been saved, do you also make confession to the Lord with all your heart, so as to receive pardon of all your sins of the time past and be accounted worthy of the heavenly gift and inherit the heavenly kingdom with all the saints in Christ Jesus, to whom be glory, world without end. Amen.
