2 Samuel 15:30-32 New American Bible (Revised Edition) (NABRE)
30 As David went up the ascent of the Mount of Olives, he wept without ceasing. His head was covered, and he was walking barefoot. All those who were with him also had their heads covered and were weeping as they went. 31 When David was told, “Ahithophel is among the conspirators with Absalom,” he said, “O Lord, turn the counsel of Ahithophel to folly!”
David and Hushai. 32 When David reached the top, where God was worshiped, Hushai the Archite was there to meet him, with garments torn and dirt upon his head.
