First, the righteous man, who repents his misconduct as soon as he becomes aware of his sin. This is the best and most complete. Secondly, of the man who has for some time led a life of sin, yet who, in the vigor of his days, gives over his evil ways and conquers his wrong inclinations. As Solomon has said, "Remember thy Creator in the days of thy youthful vigor." While in the prime of life abandon thy evil ways. Thirdly, of the one who was prevented by some cause from the commission of a contemplated sin, and who truly repents his evil intention. "Happy is the man who fears the Lord," said the Psalmist. The man, not the woman? Aye, all mankind. The word is used to denote strength; those who repent while still in their youth. Fourthly, of the one who repents when his sin is pointed out to him, and he is rebuked for the same, as in the instance of the inhabitants of Nineveh. They repented not until Jonah proclaimed to them, "Yet forty days more, and Nineveh shall be overthrown." The men of Nineveh believed in God's mercy, and though the decree had been pronounced against them, yet they repented. "And God saw their work, that they had returned from their evil ways, and God bethought Himself of the evil which He had spoken that He would do to them, and He did it not." Therefore say the Rabbis, "Our brethren, neither sackcloth nor fasting will gain forgiveness for sins; but repentance of the heart and good deeds; for it is not said of the men of Nineveh, 'God saw their fasting and sackcloth,' but 'God saw their work, that they had turned from their evil ways.'" Fifthly, of those who repent when trouble befalls them. How much nobler is this than human nature! Instance Jephtah: "Did ye not hate me ... and why are ye come unto me now when you are in distress?" But the infinite mercy of our God accepts even such repentance; as it is written, "When thou art in tribulation, and all these things have overtaken thee ... then wilt thou return unto the Lord thy God." Founded upon this is the proverb of the fathers, "Repentance and good deeds form a shield against punishment." Sixthly, the repentance of age. Even when man grows old and feeble, if he repents truly, his atonement will be received. As the Psalmist says, "Thou turnest man to contrition, and sayest, 'Return, ye children of men.'" Meaning, man can return at any time or any age, "Return, ye children of men." Say the Rabbis, "Although a man has been righteous in his youth and vigor, yet if he rebels against the will of God in his old age, the merit of his former goodness shall be lost to him, as it is written, 'When a righteous man turns away from his righteousness and doeth wrong, and dieth therefor; through his wrong which he hath done must he die.' But a man who has been wicked in his early days, and feels true sorrow and penitence in his old age, shall not be called 'wicked' any more. This, however, is not gracious penitence when it is so long delayed."
