Matthew Poole and continuators on 2 Samuel 7:17

17 According to all these words, and according to all this vision, so did Nathan speak unto David .

Although it was contrary to his own opinion, and an evidence of his rashness and folly. This therefore is here mentioned as an evidence of his Fidelity and Impartiality, in relating the whole mind of God herein, and of his modesty in taking shame to himself.
