2 Samuel 15:30-31

30And David was going up the ascent of the Mount of Olives, weeping as he went, and 1his head was covered, and he was walking 2barefoot. Then all the people who were with him each covered his own head, and they were going up, weeping as they went. 31Now someone informed David, saying, “3Ahithophel is among the conspirators with Absalom.” And David said, “Lord, please 4make the advice of Ahithophel foolish.”
