Revelation 20:15 ASV

¹³  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 man according to their works.

¹⁴  And death and Hades were cast into the lake of fire. This is the second death, 'even' the lake of fire.

¹⁵  And if any was not found written in the book of life, he was cast into the lake of fire.
