2 Bible Verses about Keys Of Death And Hades

I am he who lives and was dead; and behold, I am living for ever and ever; and I have the keys of the unseen world, and of death.

And I saw the dead, small and great, standing before God; and the books were opened: and another book was opened, which is the book of life; and the dead were judged out of the things written in the books, according to their works. And the sea gave up the dead that were in it; and death and hades gave up the dead that were in them: and they were judged every one according to his works. And death and hades were cast into the lake of fire: this is the second death.
