Tosefta untuk Amos 2:3

They publicize one who profanes [God's name] because this is a desecration of the Name, as it is said (Ez. 3:20), "And if a righteous man abandons his righteousness and does wrong, when I put a stumbling block before him, he shall die." Thus, it is publicized. Rabbi Yosei says, if a man sins once, twice, or three times, they pardon him. Four -- they do not pardon him, as it is said (Ex. 24:7), "forgiving iniquity, transgression, and sin, and cleansing." Until that point, he is cleansed, from that point forward, he is not cleansed, as it is said (Amos 2:3), "For three transgressions of Israel, [(but) for four, I will not revoke it]." And it says (Job 33:29), "Truly, God does all these things, two or three times [to a man]." And it says (Prov. 25:17), "Visit your neighbor sparingly, etc."
