2 Samuel 16:21-23 American Standard Version (ASV)

21. And Ahithophel said unto Absalom, Go in unto thy father’s concubines, that he hath left to keep the house; and all Israel will hear that thou art abhorred of thy father: then will the hands of all that are with thee be strong.

22. So they spread Absalom a tent upon the top of the house; and Absalom went in unto his father’s concubines in the sight of all Israel.

23. And the counsel of Ahithophel, which he gave in those days, was as if a man inquired at the oracle of God: so was all the counsel of Ahithophel both with David and with Absalom.
