14 All of these apply only against one who was ostracised because he insulted the disciples of the wise, but one who was ostracised on account of other matters which carry a penalty of ostracism, even though the ostracism was pronounced by the smallest one in Israel, both the president and all Israel are obliged to follow the custom of ostracism against him until he will repent himself from the thing on account of which he was ostracised, when the stigma may be removed from him. On account of twenty-four different offenses the punishment of ostracism is inflicted upon a person, whether it be man or woman. They are: (1) he who disgraces the wise even after his demise; (2) he who disgraces a messenger of a tribunal; (3) he who calls his fellow a slave; (4) he whom a tribunal summoned to appear and set a date for his appearance and he did not come; (5) he who scoffs at a matter enacted by the scribes, needless to say, a matter mentioned in the Torah; (6) he who did not carry out a judgment of a tribunal is ostracised until he will comply; (7) he who keeps in his premises something which may cause damages, such as a bad dog, or a broken step ladder, is ostracised until he will remove the damaging article; (8) he who sells his immovable property to an idolater is ostracised until he will assume responsibility of any mishap that may be brought about by the idolater against his fellow, the Israelite, his erstwhile adjoining neighbor; (9) he who testifies against an Israelite in the idolatrous court, and judgment is obtained against him as a result of his evidence to pay money contrary to the laws of Israel, is ostracised until he will make restitution; (10) a priest who is a butcher and does not separate the priestly gifts and give them to another priest is ostracised until he will give; (11) he who disgraces the second day of a holiday in Diaspora, even though it is but a custom; (12) he who does servile work during the afternoon of Passover Eve; (13) he who mentions the Name of Him Who is in heaven in vain or takes oath by the Name in non-essential matters; (14) he who causes many to commit blasphemy against the Name; (15) he who causes many to eat holy food without; (16) he who calculates years and appoints months in Diaspora; (17) he who causes the blind to stumble; (18) he who deprives many of performing a mandatory commandment; (19) a butcher who underhandedly deals out terefah; (20) a Sho'het who practices She'hita without having his slaughtering knife examined by and obtained authority from a Rabbi; (21)he who consciously brings on erection; (22)he who divorced his wife and then forms a partnership between himself and her, or establishes a business which brings them together, when they appear before a tribunal, they should be ostracised; (23) a scholar of a universally evil reputation; (24) he who excommunicates one who was not guilty of an offense punishable by excommunication.
