Deuteronómio 2:6 Halajá: Mishneh Torah, Repentance

Among this group of twenty-four are five transgressions which block the way of repentance against the sinners, they are: (1) he who secedes from the community, for he would be absent at the time they repent and could not acquire aught in their virtuous performance; (2) He who opposes the decisions of the sages, for his opposition to them brings about his own separation from them, and he knows not the path leading to repentance; (3) he who disdains the precepts, for as they appear debased to him he does not pursue after them nor perform them, and without performance what virtue can he attain? (4) he who insults his masters, for such conduct brings about his displacement and repudiation, even as it happened to Gehazi²See II. Kings, 4.1G., and being repudiated he will not find a teacher to guide him to the path of truth; (5) He who despises criticism for he, indeed, left no path open for repentance, as it is criticism that begets repentance. Forsooth, when a man is informed that his sins are known, and that he should be ashamed of himself for his wrongdoings, he does repent. For example: it written in the Torah: "Remember, forget thou not, how thou didst make the Lord thy God wroth in the wilderness; from the day that thou didst go forth out of the land of Egypt, until ye came unto this place, ye have been rebellious against the Lord" (Deut. 9.7), and: "But the Lord hath not given you a heart to know" (Ibid. 29.3), and: "A foolish people and unwise" (Ibid. 32.6); and Isaiah, likewise, rebuked Israel and exclaimed: "Ah sinful nation!" (Is. 1.4) and, "The ox knoweth his owner" (Ibid. –3), and, "Because I knew that thou are obstinate" (Ibid. 48.4). Almighty, too, charged him to rebuke the sinners, saying: "Cry aloud, spare not" (Is. 58. 1). In like manner did all of the prophets criticise Israel until they turned in repentance. It is, therefore, necessary to appoint over each and every community in Israel a great scholar of mature age, God-fearing since his early youth, and loved by them, people, to preach to the public and turn them to repentance. But he who despises criticism does not come to hear the preacher and does not pay attention to his words, he, therefore, holds on to his sins, which to his eyes appear to be good.³Alfasi, Yoma, Chapter 8. 7a. G.
