Alma 22:14 teaches "that the sting of death should be swallowed up" due to Jesus's death and resurrection.
Alma 22:14, The Book of Mormon, The Church of Jesus Christ of Latter Day Saints, accessed February 7, 2023
14 And since man had fallen he could not merit anything of himself; but the sufferings and death of Christ atone for their sins, through faith and repentance, and so forth; and that he breaketh the bands of death, that the grave shall have no victory, and that the sting of death should be swallowed up in the hopes of glory; and Aaron did expound all these things unto the king.
