“Absalom went in to his father’s concubines before the eyes all Israel.” This act of Absalom fulfilled Nathan’s prophecy that because David had taken another man’s wife and slept with her secretly (i.e., with Bathsheba), his wives would be taken by another man, who would sleep with them publicly (2 Sam. 12:11). The phrase “all Israel” tells us that many of the leaders of Israel were following Absalom at this time. The phrase “before the eyes of” is actually quite literal of the City of David. It was quite small, and people could see the palace roof quite clearly from most of the city.
