David fled Jerusalem as Absalom rebels

Then a messenger came to David, saying, “The hearts of the men of Israel are with Absalom.” David said to all his servants who were with him at Jerusalem, “Arise and let us flee, for otherwise none of us will escape from Absalom. Go in haste, or he will overtake us quickly and bring down calamity on us and strike the city with the edge of the sword.” (2SA 15:13-14)
