That is to say, the end-result of the second death is saying goodbye to life forever, sleeping a perpetual sleep from which there will be no resurrection.
Thus, the prophet Jeremiah wrote concerning the final destiny of the wicked Babylonians: “And I will make drunk her princes, and her wise men, her captains, and her rulers, and her mighty men [Revelation 6:15-17]: and they shall sleep a perpetual sleep, and not wake, saith the King, whose name is the Lord of hosts.” (Jeremiah 51:57) ."
