2 Samuel 15:31; 2 Samuel 24:10

31 Now someone told David, saying, "Ahithophel is among the conspirators with Absalom." And David said, "O LORD , I pray, make the counsel of Ahithophel foolishness."

10 Now David's heart troubled him after he had numbered the people. So David said to the LORD , "I have sinned greatly in what I have done. But now, O LORD , please take away the iniquity of Your servant, for I have acted very foolishly."
