Musar su I Samuele 25:34

The worshipper should know that when he plans to do a good deed and it comes out quickly, he should recognize that he has found favor in the eyes of his God, and that the Creator loves him. If he should wish to commit a transgression and there happen to him things which trouble him and he cannot complete the sinful act, let him know that he has found favor in the eyes of his God, as was the case with David, of blessed memory, as it is said (1 Samuel 25:34), “For in every deed, as the Lord, the God of Israel liveth, who has withholden me from hurting thee.” So one who has been spared from committing a transgression should recognize that the Creator has chosen his service and his prayer and guards him from occupying himself with filthy deeds, so that he may be pure and holy to serve his God. For this reason, every man ought to help the intellect, and in this way the intellect will be stronger than the evil inclination. If a man should commit a transgression and his evil inclination triumphs over him until he has done his desire, he should repent after he has done the deed, and he should worry and be astonished [over what he has done.] If he does this, it will be a sign that he will improve his deeds as time goes on. If a man should grieve at any one of the following three times, there is hope that in the end he will improve his deeds: First, before he commits the transgression; second, while he is still committing the transgression, and, third, after he has committed it. When one repents before he commits a transgression, that is the best of all, and when one repents after he has done the transgression, that is the worst of all. This is like one who is filled with remorse and repents at the time of his death, but who did not remember his God when he was in his full health, when he trusted in his continued tranquility, and, therefore, there is no benefit in such remorse.
