2 Samuel 16:20-23

(20) Then said Absalom to Ahithophel, Give counsel among you what we shall do. (21) And Ahithophel said unto Absalom, Go in unto thy father's concubines, which he hath left to keep the house; and all Israel shall hear that thou art abhorred of thy father: then shall 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 counselled in those days, was as if a man had enquired at the oracle of God: so was all the counsel of Ahithophel both with David and with Absalom.

How strikingly fulfilled were the denunciations of GOD by the prophet upon David in this instance! How improbable when they were delivered, and yet how fully brought to pass. See 2 Samuel 12:11. But what an awful state must all Israel have been in at this time! when the counsel of such a wicked man as Ahithophel, as by this advice he proved himself to be, was considered as the oracle of GOD! LORD! keep thy church, keep thy people from the counsel of the ungodly, and give both according to that sweet promise, Pastors after thine own heart, which shall feed them with understanding and knowledge: Jeremiah 3:15. Remark, Reader, what a connection between David's sin and David's punishment. From the housetop David first conceived lust for Bathsheba: on the housetop David's concubines shall be dishonored.
