2 Samuel 15:30-31

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 {was} with him covered every man his head, and they went up, weeping as they went up. {and wept...: Heb. going up and weeping} And {one} told David, saying, Ahithophel {is} among the conspirators with Absalom. And David said, O LORD, I pray thee, turn the counsel of Ahithophel into foolishness.
