Sanhedrin 92B

ואם תאמר: אותן שנים שעתיד הקדוש ברוך הוא לחדש בהן את עולמו, שנאמר: ״ונשגב ה׳ לבדו ביום ההוא״, צדיקים מה הן עושין? הקדוש ברוך הוא עושה להם כנפים כנשרים, ושטין על פני המים, שנאמר: ״על כן לא נירא בהמיר ארץ ובמוט הרים בלב ימים״. ושמא תאמר: יש להם צער? תלמוד לומר: ״וקוי ה׳ יחליפו כח יעלו אבר כנשרים ירוצו ולא ייגעו ילכו ולא ייעפו״.

And if you say: During those years when God is destined to renew His world, as it is stated: “And YHWH alone should be exalted on that day” (Isaiah 2:11), what are the righteous to do? How will they survive? God will make wings like eagles for them and they will fly over the surface of the water, as it is stated: “Therefore, we will not fear when God changes the land, and when the mountains are moved in the midst of the sea” (Psalms 46:3). Although God will renew the land, they will not fear, because they will be in the sky over the sea at that time. And lest you say that they will endure suffering from flying uninterrupted for an extended period, the verse states: “But they who wait for YHWH should renew their strength; they should mount up with wings as eagles; they should run, and not be weary; they should walk, and not tire” (Isaiah 40:31).

ונילף ממתים שהחיה יחזקאל? סבר לה כמאן דאמר: באמת משל היה.

The Talmud suggests: And let us derive from the dead that Ezekiel revived (see Ezekiel, chapter 37) that the resurrected dead will not live forever, but will die at some point. The Talmud explains: The school of Eliyahu holds in accordance with the opinion of the one who says: In truth, Ezekiel’s depiction of the dry bones that came to life was a parable, from which nothing can be derived with regard to the nature of resurrection.
