2 Samuel 12:13

And David said unto Nathan, I have sinned against the Lord,
&c.] Which confession, though short, was a full one, arising from a thorough conviction of the evil of the sin he had been guilty of, accompanied with real brokenness of heart, sincere humiliation, and a sorrow after a godly sort, as the fifty first psalm, that penitential psalm composed upon this occasion shows, ( Psalms 51:1-19 ) :

and Nathan said unto David;
being fully satisfied with the sincerity and genuineness of his repentance, of which he gave proof by words and deeds, and being under the direction and impulse of the Spirit of God:

the Lord hath put away thy sin;
would not charge it upon him, impute it to him, or punish him for it, but freely and fully forgive it, cast it behind his back, and into the depth of the sea; cause it to pass from him and never more bring it against him, and which is the Lord's act, and his only, against whom sin is committed:

thou shall not die;
though he should die a corporeal death, yet not by the immediate hand of God, or by the sword of justice as a malefactor, a murderer, and adulterer, as he, according to the law, deserved to die; nor should he die a spiritual death, though his grace had been so low, and his corruptions had risen so high; nor an eternal death, the second death, the lost wages of sin.
