Ahithophel said to Absalom, “Your father left some of his slave women here to take care of the house. Go and have sexual relations with them. Then all the Israelites will hear how you humiliated your father, and they will be encouraged to give you more support.”
Someone told David, “Ahithophel is one who joined in Absalom’s plot against you.” Then David prayed, “Lord, I ask you to make Ahithophel give only foolish advice.”
But if you go back to Jerusalem, you can disagree with Ahithophel and make his advice useless. Tell Absalom, ‘King, I am your servant. I served your father, but now I will serve you.’
