21 And Ahithophel said to Absalom, Go in to your father's concubines, whom he left to keep his house; and all Israel shall hear that you have dishonored your father; and the hands of all that are with you shall be strengthened.
22 And they pitched a tent for Absalom on the roof, and Absalom went in to his father's concubines in the sight of all Israel.
