2 Samuel 15:31; 2 Samuel 15:34

31 Now David had been told, “Ahithophel is among the conspirators with Absalom.” So David prayed, “LORD, turn Ahithophel’s counsel into foolishness.”

34 But 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.
