2 Samuel 15:13-14; 2 Samuel 15:30

13 And a messenger came to David, saying, "The hearts of the men of Israel have gone after Ab'salom."

14 Then David said to all his servants who were with him at Jerusalem, "Arise, and let us flee; or else there will be no escape for us from Ab'salom; go in haste, lest he overtake us quickly, and bring down evil upon us, and smite the city with the edge of the sword."

30 But David went up the ascent of the Mount of Olives, weeping as he went, barefoot and with his head covered; and all the people who were with him covered their heads, and they went up, weeping as they went.
