2 Samuel 15:29

27The king said also to Zadok the priest, “Aren’t you a seer? Return into the city in peace, and your two sons with you, Ahimaaz your son and Jonathan the son of Abiathar.

28Behold, I will stay at the fords of the wilderness until word comes from you to inform me.”

29Zadok therefore and Abiathar carried God’s ark to Jerusalem again; and they stayed there.

30David went up by the ascent of the Mount of Olives, and wept as he went up; and he had his head covered and went barefoot. All the people who were with him each covered his head, and they went up, weeping as they went up.

31Someone told David, saying, “Ahithophel is among the conspirators with Absalom.” David said, “LORD, please turn the counsel of Ahithophel into foolishness.”
