2 Samuel 15:30-34

30But David continued up the Mount of Olives, weeping as he went; his head was covered and he was barefoot. All the people with him covered their heads too and were weeping as they went up.

31Now David had been told, “Ahithophel is among the conspirators with Absalom.” So David prayed, “ LORD, turn Ahithophel’s counsel into foolishness.” 32When David arrived at the summit, where people used to worship God, Hushai the Arkite was there to meet him, his robe torn and dust on his head. 33David said to him, “If you go with me, you will be a burden to me. 34But if you return to the city and say to Absalom, ‘Your Majesty, I will be your servant; I was your father’s servant in the past, but now I will be your servant,’ then you can help me by frustrating Ahithophel’s advice.
