21Ahithophel replied, “Sleep with your father’s concubines, whom he has left to keep the palace. When all Israel hears that you have become a stench to your father, then the hands of all who are with you will be strengthened.”
22So they pitched a tent for Absalom on the roof, and he slept with his father’s concubines in the sight of all Israel.
