Mark 9:44
[Where the worms that eat them do not die, and the fire is not quenched] — some manuscripts include this verse as a repetition of verse 48; it is likely a scribal addition repeating the Isaiah 66:24 citation. Most critical texts place it in brackets or omit it. The reference to undying worms and unquenched fire is from Isaiah 66:24, the final verse of Isaiah, which describes the bodies of those who rebelled against God lying outside the restored Jerusalem.
