“‘[…] They will sleep a lasting sleep,
From which they will not wake up,’ declares Jehovah.”
~Jeremiah 51:39

The Bible explains that there are at least two different types of deaths.
One is the death of someone whom God will resurrect in Paradise, a death Jesus likened to sleep. (Luke 23:39-43; John 11:11-13)
The other death the Bible refers to is that which results in nothingness, nonexistence, simply dust and ashes. (Gen. 3:17,19; Isa. 66:24; Luke 12:4,5; Rev. 20:15)
God foretold through his prophet Jeremiah that Babylon’s leaders would receive permanent punishment for the war crimes they committed, reiterating in verse fifty-seven that they would not benefit from the resurrection hope. (Jer. 51:6, 9, 24, 25, 35, 47, 49, 56)
This prophecy was fulfilled in the year 539 b.C.E., when the city fell in one night to the Mede and Persian armies while the empire’s leaders celebrated a banquet. (Daniel 5:1-3, 30)
Because Jehovah God has appointed his son Jesus as judge, it is unwise for us to speculate whether someone who does not serve God today will not benefit from the resurrection in Paradise. (Acts 10:36,42)
