Those who sleep will awake
Whether Daniel speaks of bodily resurrection, and who 'the many' and 'the wise' are.
Daniel 12:1-4
1“At that time Michael will stand up, the great prince who stands for the children of your people; and there will be a time of trouble, such as never was since there was a nation even to that same time. At that time your people will be delivered, everyone who is found written in the book.
2Many of those who sleep in the dust of the earth will awake, some to everlasting life, and some to shame and everlasting contempt.
3Those who are wise will shine as the brightness of the expanse. Those who turn many to righteousness will shine as the stars forever and ever.
4But you, Daniel, shut up the words, and seal the book, even to the time of the end. Many will run back and forth, and knowledge will be increased.”
What each tradition says
Rabbinic / Midrashic
The Jewish Encyclopedia states that Daniel 12:1-4, about 165 B.C., looks forward to a resurrection of "many . . . that sleep in the dust." This resurrection includes both righteous and wicked, some awakening to everlasting life and others to "shame and everlasting contempt."

Patristic
Augustine says Daniel’s “many of them that sleep in the mound of earth” should not be supposed a difference from the Gospel’s “all who are in their graves.” For in Scripture, “many” is sometimes used for all.

Catholic
Haydock says “many” shows the great number, and all shall rise again. He adds that in a figurative sense the Jews who seemed buried shall appear and fight. The text is express for eternal happiness or misery, with “to see” in Hebrew meaning “everlasting.”

Orthodox
John of Damascus takes the words “many of them that sleep in the dust of the earth shall awake” to show clearly that there will be a resurrection of bodies.

Reformed / Protestant
Calvin says the word “many” seems here clearly put for all. The angel does not use it in contrast with all or few, but only with one. Some Jews strain it to mean the restoration of the Church in this world under themselves, which Calvin calls perfectly frivolous.

Evangelical
Albert Barnes states that in Scripture the word "many" is sometimes used to denote the whole considered as constituted of many. He cites Romans 5:15 and 5:19, where he says no one can well doubt that "many" denotes all, the many making up the human race, or the many offenses committed.
