Observation: Kesuvos (104b) discusses two judges who made decrees, i.e. Admon and Chanan ben Avishalom.

R. Tam's text: The text is Avishalom [and not Avshalom], because R. Meir (Sanhedrin 103b) says that Avshalom has no share in the world to comeף

We find the name Avishalom regarding Avyam. "His mother was Ma'achah Bas Avishalom" (Melachim 1:15:2).

Note: Divrei ha'Yamim 2:11:20 says that Avya's mother was Ma'achah Bas Avshalom." The Ya'avetz, and the Rashash's last answer, say that both verses allude to Avshalom ben David.

Opinion #1: Similarly, in Shabbos (12b), the text is Hillel and Shechna (not Shevna), for Shevna was a Rasha;

Opinion #2: Some say that there were two Shevna's, like it says in Yeshayah (22:15) "Lech Bo El ha'Sochen ha'Zeh El Shevna Asher Al ha'Bayis", and afterwards "Mah Lecha Po." (The Navi censured him for conspiring with Sancheriv.) This connotes that he was a Rasha;

It says afterwards (37:1,2) "va'Yhi k'Shmo'a ha'Melech Chizkiyahu va'Yikra... v'Es Shevna ha'Sofer v'Es Ziknei ha'Kohanim Miskasim ba'Sakim." (Shevna was pained to hear Sancheriv's threats!)

Inference: This was a different Shevna. Since one of them was a Tzadik, we use his name. (If so, the text in Shabbos could say Shevna.)

Rejection: Really, there was only one Shevna. We must say that the latter Shevna, who wore sackcloth in the episode with Sancheriv, was a Rasha, like it connotes in Sanhedrin (26a).

Note: The Maharsha did not understand this. The entire Sugya in Sanhedrin discusses the first Shevna!

Conclusion: Rather, the Torah is not necessarily in chronological order. (We can say that initially Shevna was pained to hear Sancheriv's threats (Perek 37), and later he conspired with him (Perek 22).)

Implied question: Here (Perek 37), Shevna is called a Sofer, and there (Perek 22) it says that he was appointed "Al ha'Bayis"!

Answer: [Even so,] you are forced to say that they were the same person, like I explained.
