Now therefore the sword shall never depart from thine house,.... During his life, and as appeared in the slaughter of his sons Ammon and Absalom before his death, and of Adonijah quickly after, and in his posterity through their wars with the children of Israel, and other nations:

because thou hast despised me; his commandments, and that in effect was despising him the lawgiver:

and hast taken the wife of Uriah the Hittite to be thy wife; which being repeated shows that it was very displeasing to God, and a very heinous crime in his sight.

The punishment answers to the sin. There is first of all (2 Samuel 12:10) the punishment for the murder of Uriah: "The sword shall not depart from thy house for ever, because thou hast despised me, and hast taken the wife," etc. "For ever" must not be toned down to the indefinite idea of a long period, but must be held firmly in its literal signification. the expression "thy house," however, does not refer to the house of David as continued in his descendants, but simply as existing under David himself until it was broken up by his death. The fulfilment of this threat commenced with the murder of Amnon by Absalom (2 Samuel 13:29); it was continued in the death of Absalom the rebel (2 Samuel 18:14), and was consummated in the execution of Adonijah (1 Kings 2:24-25).

Now therefore the sword shall never depart from thine house; because thou hast despised me, and hast taken the wife of Uriah the Hittite to be thy wife.

12:10 Never depart - During the residue of thy life.

12:1-14 God will not suffer his people to lie still in sin. By this parable Nathan drew from David a sentence against himself. Great need there is of prudence in giving reproofs. In his application, he was faithful. He says in plain terms, Thou art the man. God shows how much he hates sin, even in his own people; and wherever he finds it, he will not let it go unpunished. David says not a word to excuse himself or make light of his sin, but freely owns it. When David said, I have sinned, and Nathan perceived that he was a true penitent, he assured him his sin was forgiven. Thou shalt not die: that is, not die eternally, nor be for ever put away from God, as thou wouldest have been, if thou hadst not put away the sin. Though thou shalt all thy days be chastened of the Lord, yet thou shalt not be condemned with the world. There is this great evil in the sins of those who profess religion and relation to God, that they furnish the enemies of God and religion with matter for reproach and blasphemy. And it appears from David's case, that even where pardon is obtained, the Lord will visit the transgression of his people with the rod, and their iniquity with stripes. For one momentary gratification of a vile lust, David had to endure many days and years of extreme distress.
