David had been told, “Ahithophel, along with Absalom, is one of the people making secret plans against you.” So David prayed, “Lord, make Ahithophel’s advice look foolish.”
So return to the city. Say to Absalom, ‘Your Majesty, I’ll be your servant. In the past, I was your father’s servant. But now I’ll be your servant.’ If you do that, you can help me by making sure Ahithophel’s advice fails.
Ahithophel answered, “Your father left some concubines behind to take care of the palace. Go and sleep with them. Then all the Israelites will hear about it. They will hear that you have made your father hate you. Everyone with you will be encouraged to give you more support.”
