Parashas Vayeilech · Passuk 31:18
Yet I will keep My countenance hidden on that day, because of all the evil they have done in turning to other gods.
Torah Temimah points to Yerushalmi Sanhedrin 10:2 (ירושלמי סנהדרין פ"י ה"ב).
Sefaria — Yerushalmi Sanhedrin 10:2
English: MISHNAH: Three kings and four private persons have no part in the Future World123The Name has to be pronounced as if written אדני. It seems that he prohibits any pronunciation of YHWH even if demonstrably unhistorical (cf. Berakhot 1:1, Note 14.). Three kings: Ahab, Jeroboam, Manasse. Rebbi Jehudah says, Manasse has part in the Future World, as it is said:1242Chr. 33:13. he prayed to Him. He let Himself be petitioned, and heard his supplications, and returned him to Jerusalem, to his kingdom. They told him, He returned him to his kingdom; He did not return him to life in the Future World125R. Jehudah’s position is that of the author of Chronicles, the rabbis’ that of the author of Kings (2K. 21).. Four private persons: Bileam and Doëg126While in the Talmudim Doëg the Edomite is treated as a Jew, his being grouped in the Yerushalmi Mishnah with the Midianite Bileam, separate from the two Israelites, may indicate that for the Yerushalmi Mishnah Gentiles (at least those who are descendants of Abraham) have part in the Future World unless they act to lose it., Aḥitophel130The sin is not new; for the Yerushalmi Jeroboam has part in the World to Come. and Gehazi131Not a single golden calf but 13.. HALAKHAH: “Three kings and four private persons,” etc. All of these invented new kinds of sins. So what did Jeroboam do129To commit a new kind of sin.? Because he made two golden calves. But did Israel not make many calves130The sin is not new; for the Yerushalmi Jeroboam has part in the World to Come.? Rebbi Simeon ben Ioḥai stated: Thirteen calves did Israel make131Not a single golden calf but 13.; of these one was common property132Greek δημόσιος, -α, -ον, adj. “belonging to the people”. Also used as noun. to all of them. What is the reason? They said, these are your gods, Israel133Ex. 32:4,8.; this refers to the twelve tribes. This is your god134Neh. 9:18., i. e., one common property for all of them. So what did Aḥab do129To commit a new kind of sin.? It is written1351K. 16:31.: If it would have been too easy to follow the sins of Jeroboam ben Nevat. Are not the light sins of Aḥab the serious sins of Jeroboam? Why was Jeroboam counted first136This shows that the Mishnah underlying the Halakhah was not the Mishnah as quoted in the ms. but followed the order of the Yerushalmi: Jeroboam, Ahab, Manasse.? Because he started the misconduct. What did Aḥab do? He adorned himself every day and stood before his army commander137The word probably represents Greek στρατηλάτης “army commander”. Ḥiel, asking him, for how much am I good today? He answered him, so and so much; then he donated its value138Greek τίμησις “estimation, valuation”. to foreign worship. That is what is written1391K. 21:20. Because you sold yourself to do evil in the Eternal’s eyes.
Derash on the verse (Yerushalmi sugya) — not a formal named middah of the 13
Amoraic discussion in the Yerushalmi using this passuk; method is sugya-dialectic rather than a listed middah of R' Yishmael.
Yerushalmi’s angle on this theme stresses accountability across the covenant’s terms: hiddenness does not cancel the bond; it answers breach with distance.
