Isaiah 66:24

The worshippers would be able to view the corpses of those whom the Lord will judge. This probably includes those killed in the battle of Armageddon and those sentenced to eternal damnation. The picture is of Jerusalem-dwellers going outside the city to the Hinnom Valley, where garbage and corpses burned constantly, and where worms (corruption) and fire (holy wrath) were always working (cf. Matthew 5:22; Mark 9:43; Luke 12:5). As those who worship God rejoice before Him perpetually, so those who rebel against Him will die perpetually (cf. Matthew 25:46).

"Perhaps the most enduring lessons from the Book of Isaiah are the reminders that (a) there is a God, (b) He is coming back, and (c) our eternal destiny is determined by our response to Him in this life." [Note: Dyer, in The Old . . ., p. 587.]
