His breath goeth forth, he returneth to his earth; in that very day his thoughts perish.
Psalm 146:4
For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten. Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any thing that is done under the sun.
Ecclesiastes 9:5-6
as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
Romans 5:12
For since by man came death, by man came also the resurrection of the dead. For as in Adam all die, even so in Christ shall all be made alive. But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.
1 Corinthians 15:21-23
