And the LORD sent {a} Nathan unto David. And he came unto him, and said unto him, There were two men in one city; the one rich, and the other poor.

(a) Because David lay now drowned in sin, the loving mercy of God which does not allow his own to perish, wakes his conscience by this story and brings him to repentance.

Wesley's Notes

12:1 The Lord sent - When the ordinary means did not awaken David to repentance, God takes an extraordinary course. Thus the merciful God pities and prevents him who had so horribly forsaken God. He said - He prudently ushers in his reproof with a parable, after the manner of the eastern nations, that so he might surprize David, and cause him unawares to give sentence against himself.

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 12

2Sa 12:1-6. Nathan's Parable.

1. the Lord sent Nathan unto David-The use of parables is a favorite style of speaking among Oriental people, especially in the conveyance of unwelcome truth. This exquisitely pathetic parable was founded on a common custom of pastoral people who have pet lambs, which they bring up with their children, and which they address in terms of endearment. The atrocity of the real, however, far exceeded that of the fictitious offense.

Matthew Henry's Concise Commentary

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.
