second death, the death of the soul or spirit, the death of the resurrected person, or eternal damnation. In Matt. 10:28 a saying attributed to Jesus alludes to God as one who has the power to destroy both soul and body. A Jewish text written in the second century b.c. describes a chaotic wilderness in which fire blazes brightly. In this place the spirits of the wicked will be killed during the last days (1 Enoch 108:3-4). According to the book of Revelation, all the dead will rise on the day of judgment. Then the wicked will be cast into the lake of fire to suffer their second death (Rev. 20:11-15; 21:8).
