Daniel 12 discusses Michael's role in the end-times: he will be "the great prince" and when he will stand up, the dead will be resurrected.
Daniel 12:1-3, Old Testament, The Church of Jesus Christ of Latter-Day Saints, accessed February 26, 2022
1 And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.
2 And many of them that sleep in the dust of the earth shall wake, some to everlasting life, and some to shame and everlasting contempt.
3 And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever.
