And David said to all his servants that were with him at Jerusalem, Rise up and let us flee; for we shall not else escape from Absalom. Be quick to depart, lest he overtake us quickly, and bring evil upon us, and smite the city with the edge of the sword.

And David said to Gad, I am in a great strait: let us fall, I pray thee, into the hand of Jehovah; for his mercies are great; but let me not fall into the hand of man.
