הלכה אויף ירמיהו 3:14

Each and every one of the enumerated twenty-four different categories of persons, Israelites though they be, have no share in the World to Come. And, there are yet lesser transgressions than those referred to concerning which the sages, nevertheless, said, that he who makes a practice to violate them has no share in the World to Come, and that they are of sufficient importance to be kept at a distance, and to watch out against them. They are: he who gives an alias name to his friend; he who calls his friend by his aliases; he who shames his friend publicly; he who glorifies himself by disgracing his friend; he who insults scholars; he who insults his masters; he who despises holy times; he who profanes holy objects. That is saying, that none of these will have a share in the World to Come, if he dies without repentance; but if he repent from his wickedness and died in a state of repentance, he is, indeed, of the sons of the World to Come, as there is not a thing to stand in the way of repentance. Even if one who denied the existence of God all of his life but in the end repented, has a share in the World to Come, for it is said: "Peace, peace, to him that is far off, and to him that is near, saith the Lord; and I will heal him" (Is. 57.19). All of the wicked, and apostates and their like who turned in repentance, whether publicly or secretly, should be accepted back into the folds of Israel, even as it is said: "Return ye backsliding children" (Jer. 3.22)—though he still be backsliding, for, 10, he repented secretly and not publicly, yet is his repentence accepted.²²Pirke Abot, 3.11; Sanhedrin, 99b; Baba Mezi’a, 58b; Megillah, 28a; Tosfot, Rosh ha-Shanah, 16b; Kiddushin, 38b; Abodah Zarah, 7a.
