2 Samuel 16:22 ASV

²⁰  Then said Absalom to Ahithophel, Give your counsel what we shall do.

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.
