Megillah 25B

ומה לפנים ומה לאחור, קא משמע לן.

what was before Creation and what is after, i.e., what will be at the end of time, therefore the Tosefta teaches us that the act of Creation is read in public.

מעשה לוט ושתי בנותיו נקרא ומתרגם. פשיטא! מהו דתימא: ניחוש לכבודו דאברהם, קא משמע לן.

The Tosefta continues: The incident of Lot and his two daughters is read and translated. The name Lot begins with a lamed, the second letter of the mnemonic. The Talmud comments: This is obvious. Why might one think otherwise? The Talmud answers: Lest you say that one should be concerned for the honor of Abraham, as Lot was his nephew, and therefore the incident casts shame upon Abraham as well, therefore the baraita teaches us that this is not a concern.

מעשה תמר ויהודה נקרא ומתרגם. פשיטא! מהו דתימא: ליחוש לכבודו דיהודה, קא משמע לן שבחיה הוא דאודי.

The Tosefta continues: The incident of Tamar, beginning with a tav, and Judah is read and translated. The Talmud comments: This is obvious. The Talmud answers: Lest you say that one should be concerned for the honor of Judah, therefore the Tosefta teaches us that there is no such concern. On the contrary, the story is to his credit, as he confessed to his sin.

מעשה עגל הראשון נקרא ומתרגם. פשיטא! מהו דתימא: ליחוש לכבודן של ישראל, קא משמע לן: כל שכן דניחא להו, דהויא להו כפרה.

The Tosefta continues: The first report of the incident of the Golden Calf [egel] is read and translated. Egel begins with the letter ayin, the next letter of the mnemonic. The Talmud comments: This is obvious. The Talmud answers: Lest you say that one should be concerned for the honor of the Jewish people, therefore the Tosefta teaches us that all the more so is it amenable to them that the matter be publicized, so that they will achieve atonement through their shame.
