Verse 4. - A traveller,... wayfaring man,... man that was come to him. Nathan probably used these three terms chiefly to diversify his language, but it has served as a handle for much allegorizing. Thus Rashi explains it of covetousness, which comes at first as a mere "passer by," the literal meaning of the word rendered "traveller." But, if admitted, it grows into "a wayfaring man," who comes and goes on business, and stays a longer time. Finally it changes into "one who has come to him," and remains permanently. Such allegorical interpretations are common in the Fathers, and thus Augustine compares the three stages of sin to our Lord's three miracles of raising the dead. The sinner is at first like Jairus's daughter, just dead, and repentance can restore him immediately to life; but, if sin be persisted in, he becomes like the son of the widow of Nain, carried away to burial; and finally like Lazarus, given over to corruption.

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.And there came a traveller unto the rich man,.... By which some understand Satan, who came to David, and stirred up his lust by the temptations that offered; who is a walker, as the word used signifies, that goes about seeking whom he may devour, and is with good men only as a wayfaring man, who does not abide with them; and whose temptations, when they succeed with such, are as meat and drink to him, very entertaining but the Jews generally understand it of the evil imagination or concupiscence in man, the lustful appetite in David, that wandered after another man's wife, and wanted to be satiated with her:

and he spared to take of his own flock, and of his own herd, to dress for the wayfaring man that came unto him; when his heart was inflamed with lust at the sight of Bathsheba, he did not go as he might, and take one of his wives and concubines, whereby he might have satisfied and repressed his lust:

but took the poor man's lamb, and dressed it for the man that came to him; sent for Bathsheba and lay with her, for the gratification of his lust, she being a young beautiful woman, and more agreeable to his lustful appetite. The Jews, in their Talmud (r), observe a gradation in these words that the evil imagination is represented first as a traveller that passes by a man, and lodges not with him; then as a wayfaring man or host, that passes in and lodges with him; and at last as a man, as the master of the house that rules over him, and therefore called the man that came to him.
