Why does it say that "Yad Hashem" was on him?
Rashi: Every "Yad Hashem" in Nevu'ah is coercion. Ru'ach forced him to go like a crazed person to the place that the Ru'ach desires.
What is the meaning of "va'Yanicheni"?
Radak citing Targum Yonasan: He gave to me rest.
Which valley was this?
Sanhedrin 92b: It is the valley of Dura (where Nebuchadnetzar made an image ? Daniel 3:1).
Radak: Perhaps it is the valley where he had Nevu'ah at the beginning of the Sefer (3:22).
Of whom were the bones?
Rashi citing Sanhedrin 92b #1: They are descendants of Efrayim who left Egypt before the Ketz (deadline for redemption) - "u'Vnei Efrayim... va'Haragum Anshei Gas 1 " (Divrei ha'Yamim I, 7:21).
Radak and Malbim, citing Sanhedrin 92b #2: They are the people who denied Techiyas ha'Mesim - "...Yovshu Atzmoseinu v'Ovdah Sikvaseinu..."
Sanhedrin 92b #3: They are people who lack any moisture (tinge) of a Mitzvah - "ha'Atzamos ha'Yveshos...";
Sanhedrin 92b #4: They are people who covered the Heichal with pictures of Shekatzim u'Rmashim (insects 2 ) - "Chol Tavnis Remes u'Vhemah Sheketz v'Chol Gilulei Beis Yisrael Mechukeh Al ha'Kir."
Sanhedrin 92b #5: They are those whom Nebuchadnetzar killed in the valley of Dura. Some of the young Yisre'elim that Nebuchadnetzar exiled disgraced the sun with their beauty. The Bavli women spurted with blood (due to lust for them). Nebuchadnetzar killed the youths, but the women still spurted (the youths still radiated). He commanded to trample on the bodies.
Radak #1 (from Sanhedrin 92b): Hashem showed this to him for a Mashal Bnei Yisrael will leave Galus; they are like dry bones in Galus.
Radak #2: Hashem showed him that in the future, the dead of Yisrael will be revived at the time of salvation, so also they will see it 3 .
Radak citing Sanhedrin 92b: Efrayim mourned over them.
Maharsha (92b): They wanted to show that just like insects are short-lived, because they have no bones, also our dry bones will never be revived.
Ta'anis 30b: Everyone who mourns over Yerushalayim will merit to see its Simchah. Ritva (30b) ? they will be revived early, to see it rebuilt. Those who did not mourn over it, they can be revived in the Techiyas ha'Mesim after Yemos ha'Mashi'ach.
Did this episode truly occur, or was it a mere Mashal?
Radak citing Sanhedrin 92b #1: R. Eliezer says, they stood up, sang Shirah - "Hashem Memis b'Tzedek u'Mechayeh b'Rachamim", and died. R. Yehoshua says they sang: "Hashem Memis u'Mechayeh Morid She'ol va'Ya'al.." R. Eliezer ben R. Yosi ha'Galili says, they went to Eretz Yisrael, married women and fathered children. R. Yehudah ben Beseira: I descend from them. I have Tefilin from them!
Radak citing Sanhedrin 92b #2: R. Yehudah says, it was only a parable. Malbim ? even this opinion holds that what he saw, it is as if it occurred in practice. He sees the future, for it is present.
