2 Samuel 16:22 - Joseph Benson’s Commentary on the Old and New Testaments

So they spread a tent upon the top of the house Of the king's palace, the very place from whence David had gazed upon Bath-sheba: so that his sin was legible in the very place of his punishment. And Absalom went in unto his father's concubines To one or some of them. In the sight of all Israel Who saw him go into the tent, and thence concluded that he had converse with them as he had designed. “An action of such profligate impiety, and abandoned impudence, as it were to be wished no sun had seen, or history related.” By this we may see the character of Absalom and his party, and how abominably wicked they must have been, whom such a scandalous action tied the faster to him. And we may further learn how corrupt the body of the people were, and how ripe for that judgment, which was now hastening toward them. Now was David's adultery (which had been planned, and, it may be, perpetrated in the same place) judicially chastised, and God's vengeance denounced upon it by his prophet signally executed, and his wives prostituted in the sight of the sun, 2 Samuel 12:11. The Lord is righteous, and no word of his shall fall to the ground!
