2 Samuel 16:22-23

Young's Literal Translation

²² And they spread out for Absalom the tent on the roof, and Absalom goeth in unto the concubines of his father before the eyes of all Israel.

²³ And the counsel of Ahithophel which he counselled in those days [is] as [when] one inquireth at the word of God; so [is] all the counsel of Ahithophel both to David and to Absalom.
